A STUDY ON THE ECOLOGICAL CLIMATES OF SOME FAMOUS TEA GROWING AREAS IN HIGH MOUNTAINOUS REGIONS OF CHINA

The tea tree [Camellia sinensis (L) Kuntze] is one of the world's economic crops. It is an especially important crop for southern China. Environmental factors related to the tea yield and quality in some high mountain areas of China are identified in this paper. These factors are: geology, topography, climate, hydrology, soil and vegetation. Climatological factors are the most important. Using data collected from meteorological stations which are situated at the summit and the base of high mountains, this paper discusses ecological climatic problems in growing tea in China. The ecological climatic characteristics of the famous tea areas mainly included are as follows: more . amounts of clouds and fog, less percentage of sunshine, abundant rainfall and high relative humidity in the air, temperatures that rise and fall slowly, daily and annual temperature ranges that are smaller, more days that are suitable for tea growing and low wind speeds in the lee-sides and valleys of mountains. All of these factors     

STUDY ON THE OPTIMUM PATTERN OF DAQING URBAN SPATIAL STRUCTURE

Daqing is a mining city that was set up on wetland by exploiting and processing petroleum.This paper points out that net-group urban system is the optimization mode for Daqing urban spatial structure through analyzing and appraising the present situation,characteristics,advantages and disadvantages of Daqing spatial structure.And the best way of optimizing Daqing urban spatial structure is to adopt sustainable development strategy,establish the coordinated grade structure of urban system,construct developed towns net system,prefect the function structure of the towns at all levels,make full use of resources and strengthen environmental protection.Spatial structure of Daqing must be according-ly adjusted in order to adapt to the transformation of future economy types and functions.Bsded on the foundation of keep-ing net group,the development should be from disperse to moderate centralization in order to give prominence to the multi-function of the central city.Constructing ruralizing city should be the future goal of Daqing City.     

ON SPATIAL AND TEMPORAL CHANGES OF PRESENT URBAN POPULATION IN CHINA

Since 1949, great changes have taken place in the amount and distribution of China's urban population. From the analysis on the change in total urban population, it can be learnt that urbanization progress can be controlled mainly by social-economic development and government policy through influencing the migratory growth of urban population and the number of organic cities. In the period 1949-1990, the states of megalopolises had gone up; medium-sized cities had decreased. It is estimated that the total urban population of China will still increase at a rapid speed in the coming 10 years; there will not be great changes in grade system of urban scale; and urban population may shows a tendency to move to coastal area.

ANALYSIS ON SPATIAL FEATURES OF LUCC BASED ON REMOTE SENSING AND GIS IN CHINA

In view of the large quantities of areas,complex landform and dynamic change of resources and environ-ment in China,China has already funded abundantly a series of macro remote sensing investigation projects in land use cover change(LUCC) since 1990.Supported by the achievements of such projects,Chinese resources,environmental and remote sensing database(CRERS) was created.In this paper,we standardized the LUCC dataset of CRERS at scale of 1km,which facilitated the study of spatial features of LUCC in China.The analysis on the spatial features of LUCC and their causes of formation in China are based on the CRERS supported by the technologies of Geographic Information System(GIS) .The whole research was based on the grade index of land use,ecological environmental index and index of population density.Based on the correlation analysis,we found that the special features of LUCC were closely related with those of ecological environment and population density,which resulted form that areas with better ecological environ-ment and high production potential of land were easy and convenient for human being to live,which,furthermore,led to the aggravation of excessive exploitation of land resources there.     

STUDIES ON THE POTENTIAL OF GRAIN PRODUCTION IN THE NORTHEAST REGION OF CHINA

Northeast region covers an area of 1.24 million km, making up 12.9% of the total area of China, with a population of 103 million, 9.9% of the total population of China. The grain commodity rate is over 35%. It is one of the very important regions of grain production in China. As population and grain demand unceasingly increase, the potential of grain production, and the commodity grain provided for the nation are the major problems about grain consumption and distribution in the future. And they directly affect the realization of national planning objective of grain production.The analysis of grain production conditions and history indicates that: 1) The increase of total grain output is mainly dependent on the increase of grain yield per unit area, but not the enlargement of grain sown area. 2) The factor to affect grain yield per unit area are materials input, correct policies, yearly climatic variation. 3) By the year 2000 and 2010 the total grain output in this region will be respectively 66.16-66.2     

The economic impact of spatial organizational structures on the provincial border-regions of China

Based on the spatial organizational structures of the provincial border-regions (a border-region is one which borders two or more independent administrative regions), we build a spatial economic model for N-provincial border-regions (a N-p border-region is one which is under the jurisdiction of N provincial governments) and find that, for a given region with same geographical condition and resources endowment, the largest output of a N-p border-regional system will not exceed that of a (N-1)-p border-regional system, i.e., F₁*>F₂*...>F_N−1*>F_n*. Using the model in this paper, we present a quantitative method to calculate the economic impacts of "provincial borders" and apply it to the border-region of Shanxi, Hebei, Shangdong, and Henan provinces. The results shows that the economic potential in the border-region has not been efficiently exploited and that the annual gross agricultural products have decreased by 10.4% due to the 4-p borders.

新世纪地勘产业组织构建的理论思考

计划经济体制下形成的传统地勘产业组织 ,即地勘单位及科研院所 ,不能从根本上适应社会主义市场经济条件下的地质勘查市场的需求。现有的改组、改造方案存在较大的局限性 ,我们不得不思考一个严峻的课题 ,那就是地勘单位的灭与生。现代地勘产业组织应是投资商、作业商、咨询商三足支撑 ,多种经济成分共存的产业组织体系 ,并将项目经理部建设作为工作重点 ,虚拟组织结构建设作为发展方向。为此应建设和培育现代地勘产业组织的生存与发展的支撑条件 :即形成地质勘查法规的立法体系 ,塑造地质勘查市场的微观运行机制 ,塑造地质勘查产品的质量管理体系 ,建立地勘行业的风险管理体系 ,建设地勘产业的信息网络 ,加大地勘专业市场知识的宣传普及力度。

黄土土性的空间自相关性研究

运用土层的随机场模型研究了绛帐、潼关和延安黄土主要物理力学指标沿深度的统计规律,计算出黄土土性的自相关距离,探讨了黄土土性的空间变异性,结果认为:黄土的物理力学指标沿深度均是统计非均匀的,在实际工程的设计中,如果把土层看成统计均匀,其土性参数的标准差会比实际情况大,从而会导致较大的误差。
