    In 1981, Hayuth put forward a five-phase model that illustrates the dynamic development process of a container port system and the rationale behind such development. According to Hayuth’s model, containerization system has a profound effect on port structure and port operation, has modified some of the traditional port functions, and has introduced new dimensions to port competion, port hierarchies, and hinterland delineations. A particular emphasis is being given to the phenomenon of concentration of container traffic in few, large port load centers. In this paper, the lower Changjiang River container port system serves a case study. It can been seen that there are three development stages:(1)Initial adoption from the early 1970s to the early 1980s, only did a few large conventional ports such as Shanghai, Nanjing, Nantong port adopt containerization technology. (2) Diffusion during the period between 1986 and 1995 there occurred the obvions diffusion of the container system among the lower Changjiang River ports.The number of ports that handled container traffic doubled in this period. (3) Primary concentration of 1996 is an important lime in the deveolpment of the lower Changjiang River contain port system. By this time there occurred the most significant concentration of the container system among the lower Changjiang River ports. The container traffic that Shanghai port handled growed much faster than those of any other ports. In the author’s opinion, the present situation of this container port system is not still able to conform with the need of foreign trade and economic development at national, regional levels. The comstruction of Shanghai port as a hub of container transportation will be speed up and the comprehensive planning of the container port system will be strengthened in the future.

    It is one of the new important fields of studies on land science that optimal allocation of land use is being researched. Especially, there are a lot of problems in mountainous region, such as vulnerability of eco-environment and severity of the man-made question. Thus, there is important theoretical significance and practical value in study on the optimal allocation of the mountainous land use if on the basis of systemic analysis of the structure, function and the spatial patterns of regional land type with the landscape ecology theory and the norms of sustainable development as the guides. Structural patterns of land type are regarded as the relation both contrast of quality and quantity and spatial composition of land type in appointed area. Analyzing the structural pattern can be veneficial to reveal the heterogeneity and order laws of structure and function of land type, thus, these theoretical principles can provide us scientific basis to know roundly the ecological characteristics and succession disciplinarian of land type groups, and conduct scientifically the practice of land use allocation. In this paper, taking Qinling north slope of Shaanxi Province as an example, the structural multiclass, functional multivariate and spatial arrangement of the land type patterns are put forward based on the systematic analysis of the spatial, quantitative and qualitative structure of land types. Finally, the designs of optimal allocation models in mountainous land use have been finished, namely regional model in macrostructure, industry model in mid-scope and micro management model. The optimal allocation scheme of land use, whose essences is the optimization of structure and layout of industrial land used in the mid-scale, is one of the reification form of allocation models of land use and it has better applicability and operability in land use practice. However, the optimal scheme will be carried into execution not only brought into the regional general plan of land use and other expert plan, but also connected with the economic and social factors including the inputs of fund, technology and labor and the change of ethical ideas in the optimal allocation process of land use.

    利用乌鲁木齐河源1号冰川初始消融季节的连续雪坑离子浓度剖面,初步探讨本区冰川雪层中离子淋溶作用的特征及其对雪冰化学记录的影响。结果表明原始积雪内的大部分化学成分随融水向下渗浸,并富集在雪/冰界面处或附加冰内。当冰川消融进一步加剧、导致大部分离子成分随融水进入冰川径流,则会最终形成离子浓度很低的冰川冰,冰芯之定量记录将蜕变为定性结果。另有证据表明各离子间不仅存在淋溶择优性,而且各离子在不同淋溶阶段被淋滤的程度也具有较明显的差异。
    The successive main ion profiles of the snowpit samples collected from No.1 Glacier at the head of the Urumqi River during the early ablation period of 1996 were compared to investigate the factors that affect the re-location of the ionic species within the glacier snowpacks. It is found that most of the main ions preserved in the snowpacks since the precious melt season had percolated downwards, then were stopped at the snow/ice boundary or in the super-imposed ice layer, where layers with significantly high ionic concentrations were observed. When heavy melting happened, most of the ions might be released from the snowpacks with the glacier runoff, consequently the glacier ice with extremely low ion concentrations would form. Thus it is suggested that the ion elution processes might deteriorate the quality of ice core chemical records for paleoenvironment reconstruction. In addition, preferential elution was observed among the main ions, and the leaching degree varied significantly for different ions at different leaching stages.

    来自苏州草鞋山遗址年代学、生物地层学和沉积学的分析结果表明,本区新石器文化演进与全新世气候突变的事件有关。高分辨率、连续的孢粉、粒度和磁化率记录证实,崧泽文化是在暖湿气候条件下出现和繁荣的,发生在5365 aB.P.左右的一次干旱事件使之走向衰落,而出现在全新世大西洋期与亚北方期过渡阶段的一次气候转型事件中断了本区文明达200年之久。5160 aB.P.以后,气候转为暖干,经历了一次干旱事件后,良渚文化发展起来。
    The Eastern Plain of Taihu Lake, located at west part of the Changjiang River Delta, could cater us exceptional information both about Holocene climate changes and human activity. Most of the Neolithic culture sites in the area could be successful to serve as the proxy profiles that contain both evidence for Holocene climatic variation and vestige of human settlement. Among them, Caoxieshan cultural site, 120°45’E, 31°22’N, is most typical and could enact as a unique paradigm. High resolution and continual records of pollen, grain size and magnetic susceptibility that span 5620 years from Caoxieshan cultural site, Suzhou provide a climatic context for Neolithic culture history. The origin and flourishing of Songze cultures overlapped the Holocene Hypsithermal Interval. Prior to 5365 a B.P., the climates were sustainably humid and warm, nevertheless, at the end of Songze cultures, a serious arid event centered at about 5365 a B.P. rendered the civilization degenerate. Ultimately, a harsh cold-wet event during the transition from the warm-humid Atlantic Phase to the warm-dry Subboreal Phase uppered the lake level of Yangcheng lake group significantly, made the Songze cultures vanish and left a 200 year regional hiatus of human occupation. After 5 160 a B.P., climates conversed as dry and warm, the lake retreated, Liangzhu cultures, a relatively well-developed civilization emerged.

    藏北高原D110点不同季节土壤温度的日变化特征
    杨梅学, 姚檀栋, 丁永建, 王绍令, 陈贤章, 小池俊雄
    地理科学. 1999, 19 (6): 570-574.   DOI: 10.13249/j.cnki.sgs.1999.06.570
    摘要   PDF (556KB)
    利用1998年GAME-Tibet加强观测期间取得的一个年周期的土壤温度资料,对藏北高原D110点土壤温度日变化特征的月际变化进行了分析。结果表明,在夏半年(5~9月)土壤温度存在明显的日变化(可达40cm深处),且基本上按正弦曲线变化,但相位随深度的增加而滞后;冬半年(10~4月)土壤温度尽管也存在日变化,但变幅较小。就所研究的时段而言,6月地表土壤温度的日变化最大。一年中最低温度的变化较小且平稳;而最高温度的变化较大,尤其是9月到10月的降温过程和4月到5月的升温过程都相当剧烈。
    Based on the soil temperature data obtained in IOP period of GAME-Tibet, 1998, the monthly changes of daily variation features of the soil temperature in D110 site, the northern part of the Xizang Plateau, have been analyzed. The results show that the soil temperature existed evident daily variation in summer season (May-September). It is a sine curve and consistent with solar radiation. However, the phase lagged as the depth increase. In winter season (October-April), there was also daily variation, but the amplitude was relatively small. As to the study period, the maximum daily variation appeared in August 1997. Then it decreased. In May 1998, the daily variation increased suddenly and reached to the highest point in June 1998. Meanwhile, the variation of the minimum temperature was small and gentle, but the maximum was large. In summer, the daily variation of the soil temperature at 40 cm depth is also evident. Its variation is fundamentally a sine curve and consistent with solar radiation. However, its phase is lagged as the depth increase. The transport direction of energy between surface and its below layer could change two times in summer. In winter, although the soil temperature showed relatively evident daily variation and played as sine curve, the temperature on surface was always below that of under layer. Even the surface could absorb the solar energy, but it was too little. The energy was transported from lower layer to upper layer all the day in winter.
