According to Prof. Zhu Kezhen’s(Chu. K. C) historical climatic division, the last 500 years in China can be divided into several alternately cold and warm periods. The periods of 1470-1520, 1620-1720,1840-1890 had cold winters, while those of 1550-1600,1770-1830 had warm winters. Based on such a division, in four kinds of periods, i. e cold, warm, cold-warm and warm-cold(transition period), the differences between flood/drought degree in 120 stations in China and the average of flood/drought degree in the last 500 years have been calculated. Positive anomaly indicates drought-prone area, while negative anomaly indicates flood-prone area. This historical experience provides a background to analyze the possible scenarios in the case of global warming in the future. The final results suggest that in the case of global warming the disaster of flood probably increase in many parts of China, such as southeast coastal area, the southwest, northwest, some parts of northeast and Inner Mongolia while the disaster of drought probably decrease in the North China Plain, the middle reaches of the Huanghe River and its southern adjacent area. This distribution resembles that of precipitation in warming period in this centruy and that resulted from climatic model in the case of Co₂ doubling.

通过建制镇的发展、地域差异和空间演化的研究,宏观地再现中国近40多年来的城市化过程.尽管中国建制镇经历了一个曲折的发展过程,但总体上讲,中国建制镇的增长是一个浙进的城市化过程,中国事实上并不存在所谓的“反城市化”过程.
Growth of China’s small towns is a continuing process of urbanization. By the analysis of regional disparity and comprehensive development level of Chinese small towns, their development depends mainly on the regional agriculture and social development level. Their spatial distributions are restricted by population distribution and regional economic development level. China’s urbanination, just as the same of urbanization in developed countries, is a sign of socio-economic vigour and prosperity, is not related to social and political systems. Thus, it is worth to discuss China’s anti-urbanism with abroad scholars.

阐述了东北区经济地域系统形成发展的特点,揭示其经济地域系统形成发展机制转变过程中存在的主要问题,进而提出经济地域系统建设的新思路以及地域结构类型、发展模式和区域发展战略等.
The Northeast Economic Area with a short cultivative history in its forming process of economic regional system, has connected with international markets and developed its modern industries at a relatively early time compared with other districts in China. The distribution of productive forces manifests evident continuity. International circumstances are always an extremely improtant factor in developing the regional economy of the northeast. Natural conditions and resources have exerted a tremendous influence on the regional structure.As an improtant national industrial base, the northeast has been on the decline in national economy during recent years(that is so-called"the Northeast Phenomenon"). So there ought to be a new sense of strategic standing of the northeast in China, that is, the northeast has become devoid of main resources required in developing heavy industries continuously, its economic regional type has turned into a mixed resource-processing one from a resource typed one, and the northeast ought to become a high-graded diversified industrial base. Besides the causes from industrial structure, administrative system, history and subjective respect, the innermost is that the general train of thought in developing regional economy has been deduced from the repidly changing inner conditions and outer circumstances, which results in disadvatageous situation. Changed circumstances in and out of China are a rare opportunity to the northeast’s e-conomy.New train of thought in building up regional system is:1)Break through the old self-closed, self-perfected deve loping train of thought and establish a new one based on wider reformation, wider opening and wider circulation. Attach more importance to establish widely a special position in Northeast Asia. 2)Reorganize industrial structure and raise its grade in order that the northeast will be made into the centre of interflow of commodities, and one of the economically vigorous areas in Northeast Asia. 3)Renew old regional pattern with new one.There are objectively three economic zones, three levels of economic area system, multi-grade belts and various economic type districts, so choosing regional pattern ought to be in accordance with specific features of various regions, constructing pattern of basic regional structure, establishing two-direction channals leading to the middle belt, opening frontier belt and two exits to sea in the near future.

In this paper, the models for the resource potential of photosynthesis and light-temperature of corn, rice and soybean, climate-soil resources potentials in the northeast region of China were esteablished by using the new functions that the crops yield response on temperature, water and soil resources, the geographic distribution of the potentials were analysed, too. Also, the maximum crops yield increase potential were analysed in improving and exploitting the water, thermal, soil resources conditions and agro-tech utilization. The result showed that the light, light-temperature, climate and resource potential productivity of the main crops are high in every area of northeast region and their geographic difference are quite marked. In the main areas of the northeast region, the main crops potential productivity of photosynthesis are 4-5 times that the actural mean crops yield, the light-temperature potentials are about 21,000 kg per ha, it is about 3. 5 times as large as the actural yield, the climate potential productitvty of corn and rice are about 17000 kg per ha, the soybean is 5,000kg per ha, and they are about 2.8 times that the actural yields. The resource potentials of corn and rice are about 12,000kg per ha, that of soybean is 3,500kg per ha, and they are about 2.0 times that the actural yields. The climate yield in the south area of the northeast region are about 2. 5 times that of the north. The exploitation and utilizable potentials of the resources and agro-tech are great, the crops yield could increase by 40-60 percent with improving the thermal condition in the north and east areas, it could increase by 40 percent with building irrigation work in the southwest and the Sanjiang Plain areas, it could increase by 40 percent with improving the soil ecological condition. The resource, climate and light-temperature potential productitvity of main crops are realizable progressively with making great effort.
