    By the guide of the thought of scientific development and based on the principles of ordering in time, sensitivity in space, comprehensiveness of index and tendency of forecasting, the authors build a mathematics model to show the development track in province scale, and then simulate the development track and the developmental degree, the harmonious degree, the sustainable degree of Shandong, Jiangsu, Zhejiang, Liaoning, Guangdong provinces from 1979 to 2003. From time and space aspects, firstly, the authors divided the 25 years into three phases: the slow-start phase, the rapid-growth phase and the adjust-development phase, the corresponding characteristics of each phase were given at the same time. Secondly, the authors summed up six characteristics of Shandong Province by comparing with four other provinces: (1) The population pressure was too heavy and the "reverse scale" effect was too visible. (2) The internal efficiency and external communication was little and its regional advantages did not play enough. (3) The economic efficiency was low and the government's macroeconomic regulation and control ability was too weak. (4) Social progress was slow and the difference between twon and country was too large. (5) Technology and education input was low and innovation capacity was too weak. (6) The energy efficiency was low and the energy comsumption grew quickly. Finally, the authors put forward seven suggestions to carry out the thought of scientific development and to promote sustainable development of Shandong Province: (1) Accelerate the space conformity to reestablish the space order structure. (2) Reduce the transaction cost to strengthen the interflow at home and abroad. (3) Strengthen the regulative dynamics to optimize the economic efficiency. (4) Accelerate the urbanization advancement to reduce the urban-rural difference. (5) Breakthrough the backward west region to realizes the common enrichment. (6) Increase the science and technology education investment to enhance the innovation power. (7) Enhance the production efficiency to safeguard the resources supply and demand.

    This is an empirical study about urban internationalization. The development of global city or international city in China has been debated for nearly a decade. Nevertheless, few researchers have ever shed light on the outcome of such strategies. As a case study, this paper examines the level and process of urban internationalization in Guangdong Province, the most opening region of China. The paper firstly builds a comprehensive indicator system to evaluate the level of urban internationalization. All indicators are divided into core and basic types according to their implication upon the process of internationalization. Second, based upon the quantitative data from multi-channels such as Statistical Yearbook, it calculates the international levels of 21 cities in the years of 1985, 1990, 1995, 2000 and 2003 in Guangdong Province, showing the change of urban internationalization levels of these cities during last two decades. According to the quantitative analysis, all the 21 cities are divided into three categories: rapidly growing group, continually slowly growing group and fluctuating group. This indicates that although all such cities have undertaken policies of open-door and internationalization, the extent of changes are by no means the same. In addition, both qualitative and quantitative methods are used to uncover the underlying mechanisms. Socio-economic as well as cultural and historical factors of the cities are examined. On the basis of the study, three conclusions are found. First, after two decades of market reforming, the internationalization level of the cities in Guangdong Province have largely increased. Although none of such cities are truly so-called global city, they are undergoing unprecedented restructuring closely related to global forces. As such, the strategy of open-door has successfully developed a system of globalizing cities in the region. Also, this indicates that internationalization/globalization has tremendous impact on cities on the lower level of the global city hierarchy. Second, the internationalization development is not the only phenomena of the so called Word City and Global City. Rather, it is a widespread process in nearly every city in the world. Even more, the extent of impact by internationalization upon cities is rooted in the regional context of such globalizing cities. It is highlighted that historical, political and cultural factors are significantly factors underlying the process. Different cities have undertaken varied channels to raise their status on the hierarchy of globalizing cities. Third, it is found that the change of urban internationalization is not a linear growing process, but a fluctuating process with occasional growth and decline for most cities. This shows that the process of internationalization is complicated. The level of urban internationalization is not only a result of forces oversea, but also the result of the local variables including both geographical and social conditions.

    Jiangsu Province is one of the most rapid urbanization areas in China, as the developed province along the sea and the model of rural industrialization and rural urbanization in China, the changes of the urbanization mechanism in Jiangsu exemplify the development of urbanization mechanism in China. And the paper concludes the characteristics of urbanization in Jiangsu in the 1990s. As a socialist country, up-to-down urbanization mechanism is fundamentally in urbanization process in Jiangsu. After reform and opening, bottom-up urbanization mechanism is more and more important. In the 1990s, under the economic globalization circumstances, outward urbanization become the new urbanization mechanism in Jiangsu. That is to say, the power of urbanization is changing as the development of productivity, and various developmental stages have various power structures.

    The employment issue is an important challenge that confronted the current society and economy development of China and the industrial structure evolvement is an important part in regional economic development, and they are closely related to each other. Wuhu is an important city in Anhui Province, its industrial structure has been changed quickly in the last decade and industrialization course developed rapidly. But large quantity of surplus labor force and the difficulty of its transferring is an important hindrance to the rapid and overall development of Wuhu City. This paper, from the angle of the relationship between industrial structure and employment structure, explores the mutual development of the industrial structure and employment structure. Firstly, the relationships between employment structure and three industrial structures, secondary and tertiary industries and current labor force supply and demand condition in Wuhu City have been analyzed respectively. The conclusions show that: (1) The industry development and labor force supply and demand in Wuhu City is out of line considerably; (2) The structure conversion in industry itself is an important reason for labor force transfer and market change; (3) The lack of third industry development is important limiting factor for economy development and employment extension in Wuhu City; (4) The lack of labor force employment training is an important obstacle to employment. At last, the main countermeasures to promoting mutual development of the industrial structure and employment structure include emphasizing establishing industry group, developing the servicing business strongly and strengthening the labor force occuation training facing the market.

    The authors found that the past quantitative study on regional spatial structure of the Chinese urban system that was based on the random distribution model of Poisson's equation was imperfect, because the contemporary Chinese cities did not fit the character of the random distribution. A gravity model of the cities spatial distribution was formatted by virtue of Newtonian Dynamical Equation to improve the random distribution model, and made a quantitative study of the Chinese cities by taking province-level administrative regions for spatial cells and using the data of 2002. The conclusions are summed up as follows: first, the urban spatial structure of China was composed of 6 mass-clusters of urban accumulative regions, 10 strip-clusters of urban accumulative regions and 8 urban groups with metropolis as the core; second, multi-cores and multi-clusters urban accumulative regions were mostly distributed in the east provinces of China, sole-core and sole-cluster urban accumulative regions were mostly distributed in mid-China, and large urban groups appeared in the west. The difference of cities development levels was obvious among the three zones, and gradient-phenomenon is very distinct.

    The water resources and socio-economic system (PRD) in river valley is studied in this paper by system dynamics (SD), and based on it the dynamic behaviors of PRD system in river valley are simulated under different conditions, which can be the basis of solving the problem of river valley PRD system. Taking Guanzhong segment of the Weihe River valley as an example, three PRD system models (the lineal-growth model, the feedback-growth model and the water diversion coupling model) are respectively set up by SD, and simulated by the Venple software. The lineal-growth model based on government planning objective is the pattern that society-economy can develop at a super-speed, but it can also continuously enlarge the gap between the demand and supply of water resources. The feedback-growth model could adjust to the target of socio-economic development according to the conditions of water resources carrying capacity within the river valley, yet it is difficult to fulfill the developing and driving mission that Guanzhong area takes on. The water diversion coupling model introduces water resources outside, by which the situation of water shortage can be improved clearly, also the socio-economic development can keep on increasing at a sustainable higher speed, so it is an effective way to solve the PRD problem in Guanzhong area, however, the synergy of water diversion project and society-economy becomes the critical problem to be solved at present.

    The main models of the distribution of mid-low-latitude Atlantic SST in winter and its relation with air temperature in China were researched by using NCEP/NCAR's mean SST, the height at the level of 500hPa reanalysis monthly data from 1951 to 2001 as well as the observed air temperature got from 160 observatories in China. The methods of REOF and wavelet transformation were adopted in this paper. The results show that SST anomalies in central north Atlantic in winter reflected two basic models, and the interannual and interdecadal variability of second model characteristics that can reflect SST anomalies in the field between 20癗 to 50癗 in Atlantic in winter has close relation with mean air temperature in China. In addition, the result also showed that it will result in higher air temperature when the SST anomalies in central north Atlantic in winter motivated Eurasian circulation of EU pattern.

    The soil moisture data from 33 agro-meteorological stations are employed to investigate the linear trend of soil water storage of Heilongjiang Province, north of Northeast China in recent 20 years. The results show that the whole trend of soil water storage from soil surface to top 50cm for growth season is decreasing. Moreover, not only the dry trend in mountainous regions is more significant than in plain regions, but also the climate wetness of normal regions are easier to be dry than the semi-arid region. From soil surface to top 50cm, the decreasing extent of mean soil water storage for the whole growth season over the region increases with vertical soil depth. The decreasing trend in spring and autumn are more evident than in summer. Combining the local and regional ecological and climatic characteristics, the paper discussed the disadvantageous influences of soil moisture storage on agriculture and ecology in Heilongjiang Province as well as the corresponding regulative measures and water managements.

    As water tower for human kind in the 21st century, mountains and their resources and ecology have increasingly become the focus of many studies. The Qinling Mountains serves as the climate boundary between sub-tropical and warm-temperate zone in China. Its vertical belt structure is different between the northern slope and the southern slope, and the state and type of land use accordingly differ greatly. This article makes use of satellite images in summer of 2000 and 1∶250000 digital elevation model (DEM) to acquire the data of land use types distribution on different vertical belts in order to disclose the interrelationship between montane vertical belt and land use. In Qinling Mountains 44.83% of the land is woodland, 35.93% is grassland and 18.42% is farmland. Land use change on different vertical belts is obvious. From the base belt to top, the proportion of farmland reduces to zero according to exponential curve, the woodland changes according to plus parabola and the grassland changes in inverse proportion to the woodland.Land use change on the same vertical belts is visible too, especially in Quercu variabilis forest, Q. aliena var.acutiserrata forest and Abies forest.

    A relatively high-resolution paleoclimatic change sequences was established based on a mass-spectrometric uranium-series dated stalagmite from the Jinfu Mts. Caves of Chongqing region during the late period of Last Glaciation (31.90 ka-15.21 ka B.P.). The stalagmite began to deposit at 31.90 ka B.P. and ended at about 15.21 ka B.P. without any obvious hiatus. The depositional ratio is about 1.77 mm/100a in average. A high-resolution δ18O records of the stalagmite demonstrates not only the existence of the abrupt climatic change, the Henrich events, but also bears a high similarity to the δ18O-paleotemperature record of Nanjing Hulu and Guizhou Dongge caves, indicating the paleoclimate of Chongqing region, even at the middle reaches of the Yangtz River, was confined by both the influences of Indian summer monsoon and East Asia summer monsoon at the late period of the Last Glaciation.

    There are different opinions on origin problem of the red earth in the Pleistocene, namely diluvium, alluvium, aeolian, and so on. Based on the grain-size analysis of five representative sections from the mid-subtropics, deposit-environment of the red earth is discussed in this paper. The results show that: (1) Grain-size distributions of five red earth sections in mid-subtropics are very similar,which probably indicates aeolian characteristics from their parent materials and the weathering process. The average content of 4-63 μm particle group ranges from 48.12% to 68.89%, the one less than 4μm and the one over 63μm are respectively from 23.83% to 50.10% and less than 5%. Generally speaking, the grain-size frequency curves of the red earth show the double-peak mode—the 10-63μm paticle group is "the dominated mode", and the one less than 4μm is "the secondary mode" or "the dominated mode" of some samples. (2) The particle parameters are highly correlation, which suggests that the sedimental environment of brown-yellow unit, typical red clay unit and vermiculated red earth unit are similar. However, the probability accumulation curves of red earth could be divided into two types—three-segment pattern or five-segment pattern, which maybe show the more complicated sorting-environment. (3) Mean grain-size value and content of 4-63μm particle group of brown-yellow unit are larger than those of typical red clay unit and vermiculated red earth unit.

    As a case study of purple soil on typical slope lands in the Three Gorges Reservoir region, this paper primarily explores trace element contents in purple soil and their changes under the different grades as well as the different land-use types. The result shows that the contents of Fe, Mn, Ni, Zr, Sr and Ti in purple soil in the Three Gorges Reservoir region are higher than the background values of purple soil (A layer) in China and the average value of all the soil (A layer) in Sichuan, that of Mo is very rich, but those of Zn and Pb are lower relatively than the ones of Sichuan and China. Contents of Pb, Cu and Co are decreasing along with grade increase among some grades. By contraries, the contents of Zr and Cr are increasing. The contents of Cu, Pb, Co, Ti, Zr, Ni, Cr, Sr, etc. in purple soil have some correlations with the changes of slope grades. Difference of trace element contents is remarkable between cultivated land and uncultivated land. The man-made activities are primary factors leading to the changes of trace element contents of purple soil in the Three Gorges Reservoir region.

    As a typical city of rapid urbanization, the urban land surface temperature of Dongguan City was retrieved through interpretation of Landsat TM6, combined with land use map and meteorological observational data, and three thermal effect estimating indices (thermal effect contribution index, thermal pixels proportion index, regional thermal pixels proportion index) were designed to discuss the impact of various types of land use on urban thermal environment, which shows that urban and rural construction land for industry and residence take an important role, while water area and grassland gives little impact, and the thermal contribution of heath land to regional thermal environment is the least one. The result of the three indices also proved that it maybe untrue if we only consider the contribution of average temperature to urban thermal environment. The research also shows that the average temperature in winter had obviously been increased from 1988 to 1998 in Dongguan, and the land surface temperature was 2.21℃ in 1998 higher than that of 1988,while the water surface temperature had been changed little(0.76℃),in a word, the difference in surface temperature between water surface and land surface rise sharply as the average temperature rising from 1988 to 1998.

    After the research of sedimentology, geomorphology and chronology in the Sanduizi-Wudongde reach, we come to the conclusion that the geomorphic feature of the lower reaches of the Jinsha River was formed in the late middle Pleistocene. The ancient Jinsha River was jammed in Jingpingzi and it turned into a local base level of stream, which influences the incision rate along the Sanduizi-Wudongde reach of the Jinsha River. The average incision rate of Jinpingzi, Aoga, Longjie and Yuzha are 196-217 cm/ka, 145-172 cm/ka, 257-305 cm/ka, 82-97 cm/ka respectively. Because of the tectonic knickpoints and lithology knickpoints of the Jinsha River and the distinctions of the fluvial characters, there are some differences in the valley geomorphic feature and the TL datings of the terraces between Aoga reach and Yuzha reach,so the analysis of the terraces height relative to the Jinsha River do not make out. The Sanduizi-Wudongde reach of the Jinsha River contain many kinds of heavy minerals, such as magnetite, russet iron ore, epidote,garnet, and contain many steady minerals and degenerative heavy minerals, for example zircon,rutile, white-titanium, crossed-stone, cyanite, and so on.

    Tourism and traveling behavior happens between destination and origin. The competition between different tourist destinations manifests itself in the contest for tourists from different origin regions. Reviews of relevant literatures reveal that most of the studies undertaken have been mainly focused on tourist destinations, and till now little attention has been paid to origin regions. However, it is of great significance to understand the spatial pattern of the integrative emissiveness of residents in different origin regions for the promoting and marketing of tourist destinations and the development of the tourism industry. Cities are not only important destinations, but also main tourist origin regions. Both domestic tourism receipts and capita expenditure suggest that urban residents are important tourists in the present China. Therefore 39 cities in the Spot Check of Chinese National Tourism are chosen as spatial units in this study. The methods such as principal component analysis, cluster analysis and correlation analysis are used mainly in the research. Based on the statistical data and the SPSS analytical software, spatial disparities of latent emissiveness of urban residents in China are discovered by using 18 indexes. Firstly, urban economy, urban diffusion impact, urban agglomeration impact and urban population quality are main factors relevant to the tourism latent emissiveness of urban residents. Secondly, according to the results, the capacity of the latent emissiveness of 39 cities can be divided into four types, from the strongest to the weakest respectively. Moreover, urban residents in coastal zones are more inclined to go traveling than those dwelled in inland zones. There exist three apices that have strongest latent emissiveness, i.e. Beijing, Shanghai and Guangzhou-Shenzhen. Bohai Sea Rim, Changjiang Delta, Zhujiang Delta and Chengdu-Chongqing area are found to be four important tourist generating regions in China. Then the model is well testified by the actual emissive ratio of these cities. Conclusion can be drawn that latent emissiveness is stable generally influenced by urban integrative characteristics while actual emissiveness is unstable likely to be influenced by exceptional events. However the actual emissiveness can be viewed as indicator of the latent emissiveness in term of the significant relevant relation being found between them. Two issues which we have difficulty in accounting for at present are put forward so as to settle in the near future. First, latent emissivenesses of Shanghai and Xi’an are quite different from their actual emissivenesses. The actual emissivenesses of residents in Shanghai from 1999 to 2002 kept low while the actual emissivenesses in Xi’an kept the first in the country during this period. Second, tourism emissivenesses in rural areas are not dealt with in this paper due to the length. With the development of the rural areas, it will be of necessity to give the enough attention to the tourism emissiveness in rural areas.

    In order to provide series of service for tourists, including traffic, accommodation, visiting, entertainment, shopping, etc., many people are gathered in tour area, so tourist town was emerged. This process is called tourism urbanization. Analyzing the impacts of tourism urbanization is an important part of tourism urbanization research. This paper takes Jiuhua Mountain as an example, on the basis of on-the-spot survey, studies residents’ perception of the economic, social life and environmental impacts of tourism urbanization. By comparative study, some differences of residents’ perception and attitudes are found. There are some different opinions on economic, social life and environmental impacts among the residents with different ages, genders and education degrees. The research results show that the residents have strong perception on both advantageous and disadvantageous economic effects carried by tourism urbanization, and their perception on good social life effects are much stronger than those bad, additionally, they have very strong perception on harmful environmental effects with tourism urbanization. Furthermore, the residents of different groups distinguished by age, gender, education degree, career, etc., have different perception even on a same effect factor of tourism urbanization. In the last, some countermeasures are put forward, such as selecting the rational location of tourist town, coordinating the relationship between urban planing and tourism planing, protecting the ecological environment in tour area, uniting the management of tourism industry and tourist town, etc.
