Rates or urbanization in China are increasing through heavy migration from rural areas. Four large metropolitan regions near the coast have emerged. - (DWG)
Changes of precipitation in China due to the enhanced greenhouse effect
China ; Drought ; Global change ; Greenhouse effect ; Model ; Precipitation ; Rainstorm ; Summer ; Temperature ; Winter
The AA. discuss changes of precipitation in China due to growing greenhouse gases using GCM model assuming the IPCC Scenario. An increasing greehouse effect will lead to precipitation increases mostly in north of 30°N for winter, and strongly
increases along a slant belt from Northeast China to bay of Bangal for summer. The model results are also shown to imply that an increasing greenhouse effect enhances chances of intense storms and drought for winter and summer in China.
Urban performance and the control of urban size in China
China ; City size ; Economic efficiency ; Town ; Urban policy ; Urban population ; Urbanization
The current policy of controlling city size to deter the development of large cities, seems to be either irrelevant or misleading. Instead, against a current background of rapid urbanisation, China should take full advantage of its large cities

The paper focuses on systematic and overall review of literatures on China's urban geography in recent years. Attention is particularly paid on the progress in new themes and generalization of major arguments.
The relationship of large volcanic eruption in the world and the summer drought/flood in China
China ; Drought ; Flood ; Precipitation ; Sichuan ; Statistics ; Summer ; Temperature ; Volcanic eruption ; Weather type
Based on data in the last 500 years for strong volcanic activity and the summer drought/flood types available in China, the statistical relations of the volcanic eruptions in seasons and several regions and the drought/flood types and grade index
of main regions in China have been investigated. The possible teleconnection between flood in the Yangtze River and the Haihe River valleys in 1991 and the volcanic eruption of Mt Pinatubo in June of 1991 has been also examined.
An analysis on the influence of global climatic change upon natural zones and agricultural potential productivity in China
Agricultural productivity ; Agroclimatology ; China ; Climatic warming ; Crop ; Evapotranspiration ; Global change ; Model ; Temperature ; Zonation
According to climatic, hydrological, soil and vegetation data from 671 stations in China, 12 temperate zones with 45 natural regions are identified. In this paper, methods like migration of crop distribution, potential productivity, and dynamic
Desertification in China: status, trends, and strategies

In China the desertified land area has already reached 11.6 percent of China's total land area. In recent decades, reverse trends have occurred in regions under proper control, however, on the whole it has been expanding. This paper is supposed
Lake evolution in the Tengger Desert, Northwestern China, during the last 40,000 years

Climatic changes inferred from lacustrine deposits and lake-level fluctuations in northwestern and central China are mainly based on paleoclimatic records from the Tibetan Plateau, while there is still a lack of data relating to the semiarid/arid

albedo in 22 stations in China region as test are obtained using the satellite GMS-3 in january, april, july and october 1995.
In this paper, the methods to derive the surface albedo from the satellite data are developed. In order to determine surface albedo over the China region, the corrections of altitude effect have been introduced based on ground mesure data
