    Based on the methods of new economic geography,a spatial model is built to explore the effects of natural resources on non-resource-based manufacturing location choice behavior and thus characteristics of urban location.The results show that,when the resources-based manufacturing is small,the location of natural resources is remote,and the transportation costs of resources-based manufactured goods are small,the mode of city-industrial and mining areas will be the equilibrium state of regional spatial structure.When the resources-based manufacturing has a large scale,the natural resources located near the center of the region,the resources-based manufactured goods are characterized by high transport costs,resources-based city becomes an equilibrium state.The study also shows that circular causation of demand and path dependent effects play an important role in natural resources shaping urban location.Then,based on the research,the economic mechanisms of big river development axis proposed by Mr.Lu Dadao are completed.Finally,the paper is concluded and recommendations on China’s regional practice are suggested.

    Financial Globalization is integrating the world financial system,however,the territorial differentiation of the world financial system is still very obvious.From the economic geography perspective,the world financial system presents the feature of tiers.This article has proved the existence of the tiers of world financial system by theoretical analysis and quantitative methods application.The world financial system is divided into four tiers through quantitative analysis and the features of each tier are pointed out.The countries and regions of the first tier have highly developed and extremely active financial systems.In the second tier,the financial system is comparatively sound and closely related to the real economy.Thus individuals and enterprises in the second tier are able to access to the financial services easily.The financial system of each country of this tier has its own distinguished advances comparing with other countries,however,to the whole financial system there is still some way to the first tier.There are no any developed countries that could be found in the third tier.Instead,the third tier almost composes of the emerging countries.The inadequate development of the financial system of the third tier leads to inefficiency and cumbers the economic development.And each country of the tier has its own obvious shortcoming in the financial system.The internal differentiation of this tier is notable.The financial system of the fourth tier is underdeveloped,which consists of unsound institutional environment,small-size and inefficient banking system,undeveloped financial market and a narrow range of financial instruments.Therefore,it is rather difficult for the individuals and enterprises to obtain the supports from financial system.The industry development and consumption expansion are limited by the poor financial system in the fourth tier.Furthermore,the mechanism of the geographic tiers of the world financial system is discussed.The financial system is a complicated system,and is a sub-system of the whole socio-economic system.Generally speaking,the synergy of humane geographic environment and the nature of financial system induce the differentiation of financial system on the geographic distribution.At first,the different development levels of different countries lead to the different demand for finance.Furthermore,in this article the geographic boundary or the border between countries also divides the world financial system.Finally,the heterogeneity of the financial market information on space and time causes the geographic differentiation of financial system objectively.The process and the path of financial globalization are deeply influenced by geographic tiers of world financial system.The pattern of present international financial system is also shaped by the geographic tiers of world financial system.

    Based on the coupling and coordinative characteristics of urbanization system and environment system in Guangxi,taking environment and urbanization as two composite systems respectively,through the quantitative integration measure,the paper aims at probing into the coupling interaction and coordinating relationship of urbanization and environmental system of Karst region in the southwestern Guangxi,China.In order to properly handle and coordinate the conflict between increasingly sped-up urbanization and serious ecological environment,and to provide the theory basis and the practical guidance for realizing environmental coupling and coordinated development,the paper constructs theoretical models of urbanization and environment to measure the coupling and coordinative degrees and analyze the interactive relationship between urbanization and environment of urbanization and environment composite system from 1985 to 2007 in Guangxi.The results show that the coupling degree of urbanization and environment system is low,and the time sequence of the coupling degree in Guangxi is basically at resisting stage from 1985 to 2007.The coupling degree of urbanization and environment system had risen from 0.187 to 0.500 in 1985–2001,and the system had undergone one "S" type evolutionary cycle which went across low-level coupling,antagonist,and then running phase in 2001.The degrees of coupling and coordinative between urbanization and environment system had gradually decreased since 2002,which reached the lowest position in 2007.Besides,the coupling coordination degree of urbanization and environment system is low,which are basically at low stage.This shows that the sped-up process of urbanization system in Guangxi in several years has brought more and more pressure to its environment system,so it is necessary to correctly handle and coordinate the relationship between the rapid developing urbanization and the increasingly severe environmental condition in Guangxi,and the measures should be taken as soon as possible to urge the development direction of the coupling urbanization and environment system coordinately.To change the present situation of lower coupling and coordination degrees of urbanization system and environmental system in Guangxi,and to prevent the continuing growing pressure on the environment,the government,the enterprises,together with the residents,should control their own behavior in order to response to the coupling and coordination system in time.The behavior,including policy guidance and effective implementation,application of environmental technology,the guide of market mechanism,and the strengthen of public environmental awareness,will all influence the urbanization process and the state of the environment improvement through the direct feedback mechanisms,and transform the urbanization and environment to benign coupling coordination and promote sustainable change direction together in Guangxi.

    With the leading process of the ideological trend of ‘cultural turn’,the main focus of ‘new cultural geography’ has transformed from emphasizing the results of the geographical phenomena to the process,with its spatial process and social relationships which internalized in special regional systems being more emphasized.The meanings and symbolic functions of the landscapes were reinterpreted in this transformation process.Based on the participant observation on the official activities of ancestor worship of Gelao ethnic minority which is one of the native ethnic minorities in Guizhou Province and in-depth interviews with relational groups in Wuchuan County,Guizhou Province,it is found,under the context that the economic development relies on the ethnic culture as the tourism attractions,the ethnic elites reconstructed the Jiutiantianzhu as ancestors of Gelao ethnic minority and the rituals as well as the place of ancestor worship in order to make Wuchuan County become the central place of Gelao minority groups.In the process of reconstruction,the meanings of place have been changed,and the Xiaotangshisun has also been transferred from the original natural landscape into the central cultural landscape of Gelao ethnic minority groups.Although the spatial strategy of the place being centralized as ‘the source of Gelao ethnic group’ enlarges the fame of Wuchuan County and enhances the influence of the area,there is an opposite identity on activities of ancestor worship between official ‘on-stage’ of the ethnic elites and non-official ‘under-stage’ of the common people.The essential reasons for the divarication cover two aspects.One is that the local Gelao people in Wuchuan County have not distinct memory about their ethnic group.The other reason is that the Gelao minority have been scattered so long time that they have already had different culture from place to place.In the process of the cultural practice of ancestor worship of Gelao ethnic minority,the local elites reconstruct the place identity by various kinds of the social relations and powers,meanwhile the local ethnic identity also cause some impacts on the reconstruction of place meanings in another way.It is finally pointed out in the paper that the official cultural reconstruction suspended above ethnic groups would be very fragile without the support coming from the common Gelao people from bottom to up.This study has a great theoretical significance in improving the research on sense of place with the lack of subject,and also in enhancing the study of emphasizing the importance of ethnic identity and place identity.

    In recent years,the researches on the spatial relationship of tourism destinations were halted at three directions: competition,cooperation,and cooperation-competition.However,under the influence of economic,social,and cultural factors,the spatial relationships of tourism destinations always show other different forms.The former relationship classification is so simple that it cannot deal with the complex situations.With a literature review on the domestic and abroad studies,the author found that lots of scholars began to try to explain the relationship in ecological ways.The spatial relationships between two or more destinations are described as competition,predation,symbiosis,and parasitism."Niche",as ecological terminology,has been introduced into tourism study.The purpose of this study is to apply the bionics theory to the tourism destination and to explore new methodology for the spatial relationships of destinations qualitatively and quantitatively.Thus,this paper is composed by three parts: 1) the establishment of the spatial relationship models based on ecological interpretation;2) the construction of a bionics study approach of spatial relationship among tourism destinations;and 3) the application of the new approach to Xidi and Hongcun villages as a case study.After fieldwork,data collection are analyzed,and it is found that the tourism niche of Hongcun Village is bigger than that of Xidi Village,which means the competitiveness of Hongcun is stronger than that of Xidi because of its bionics landscape,business promotion and location advantage.Xidi and Hongcun reached a stable state of competitive spatial relationship in 2006-2007,and they will keep this relationship in future.This study proves that tourism destinations’ bionics relationship approach is better than the traditional ones.It makes a more detailed and comprehensive classification of spatial relationships,which can be applied not only to the large-scale tourism destination,but also to the small-scale scenic spots.When using it,we should pay attention to the choice of niche dimensions and the calculation of tourism niche,which must be based on the reality of cases.More kinds of tourism niche calculation and deeper exploration of the connotation of tourism niche and this new approach are planned to be studied.Through putting both qualitative and quantitative research methods into the bionics relationship,this new approach will be proved to be more useful for the analysis of tourism planning and destination management.

    Crisis or disaster has increasingly influenced tourism development and tourism demands obviously.Effective tourism marketing has been widely proved to be one of the focusing measurements for tourism market recovery in many destinations which suffered no dramatic tourism attractions or facilities damages by disasters.Then study on influence of certain disaster or crisis on tourists’ motivation is very crucial for after-disaster tourism destination management and tourism market recovery after some disasters.Taking China’s Jiuzhaigou National Park as a case,the authors conducted some quantitatively comparative analyses of tourists’s motivation based on the questionnaire survey data collected in the park before(from April 27th to May 5th,2008) and after(from,May 5th to 10th,2009) the Wenchuan Earthquake on May 12th,2008.And some quantitative analytical methods such as MANOVA analysis has been used to analyze the changes of tourist motivation in the destination.Some research results can be drawn as below: 1) Tourists to Jiuzhaigou were mostly motivated by their desire of "being close to nuture" both before and after the quake.It is important to note that nature attraction of the world natural heritage was the main and common pull motivation for both short-haul and long-haul markets before and after the earthquake.On the other hand,the Wenchuan Earthquake did great influence most of the tourists’ motivations to visit this park—the importance of pulling motivation declined while that of all pushing motivation but "for social status" increased;2) Before the earthquake,tourists’ knowledge obtaining motivation(experience new things and learn about other culture) was more important than that of recreation motivation(enjoy life and enjoy tranquility),while it has reversely changed after the shock.The importance of the social and psychological motivations(for social status motivation "to see famous sights") decreased after the disaster.3) The attraction of non-core attractions in the destination has experienced distance-decay changes,while the attraction of some core attractions in the park showed no changes with distance before and after the shock.Actually,Jiuzhaigou’s tourist market segmentation within central-western China experienced adverse changes.According to the results of MANOVA,there were reverse trends between the midwest(increse) and midwest(decrease) in the change of market share before and after the earthquake.But all of these markets showed no great differences of tourist motivation.It may imply that tourist motivation can play a tiny role in the explaination of the market changes within some adajacent developing regions before and after the quake.Based on previous research conclusion,the authors put forward some differential marketing suggestions for its market recovery.

    Although the typical-sample-based prediction models of the spatial distribution of soil property are promising in digital soil mapping,the sensitivity analysis of the soil property parameter in these models is still lack.This paper presents an attempt to establish weighed average model on a fuzzy slope position based on typical samples for digital soil mapping.The soil samples of A-horizon soil organic matter were collected in a low-relief small watershed in Northeast China.A "factorial design" method was applied to simulating scenarios of modeling point set.The performances of the model under different scenarios were analyzed with box plot.Further,we designed an MR index,which was calculated from the median and the range of the prediction error,for parameter sensitivity analysis based on the prediction performance of model.Both MR index and existing sensitivity index were used in this study.The result shows that the weighed average model is sensitive to the soil property parameter.The sensitivity degree is related to the locations of typical soil sample.The method proposed in this paper is also available for the parameter sensitivity analysis of other typical-sample-based prediction models of digital soil mapping.
