Abstract |
Water scarcity and regional maldistribution is always the constraint for Chinese development. Since the late 1970s, China has stepped into the accelerating phase of urbanization, which has boosted the water consumption of Chinese urban area. At present, there are two thirds Chinese cities are suffering from water shortage, and about 100 cities are extremely lack of water supply. Most existing studies have discussed related issues on national or regional scale from the perspectives of the water resource sector, but little research has focused on the scale of urban level and the potential demand and influence of Chinese future urban development to water resource management. Accordingly, based on the water-related statistical data from China City Statistic Yearbook and public statistical reports of the specific cities, this paper intends to utilize the approach of spatial analysis and spatial statistics to estimate the water resource capacity of the 285 Chinese prefecture-level cities under the stress of future urbanization process, which will help to identify and indicate the potential and feasibility of Chinese cities to accommodate the newly emigrated population from the rural area and the suitability to further accumulate or develop related industries. Specifically, the major study content includes: (1)The hydrological background analysis of the study cities from the regional scale (precipitation, evaporation, hydrogeological condition etc. ); (2)Water resource condition analysis of the study cities(sum, surface water, ground water, dominant water resource type, diversity and stability in supply etc.); (3)Analysis of water related infrastructure of the study cities (water supply, sewage, drainage, reclaimed water, grey water, treatment plant infrastructure etc.); (4)Analysis of water consumption in industries and urban life (water use in agriculture, manufactory industry, service industry, and household use etc.) of the study cities; (5)Present and future water balance analysis and calculation of the study cities; (6)Discussion about the optimization strategies of demographic distribution from the perspective of water resource and other related factors, which could lead Chinese urbanization process towards more sustainable routes in the future. The prospect contribution of this paper is to study water resource related issues at a more detailed spatial scale and from the perspective of urban studies. By identifying the water resource capacity and constraint factors of different prefecture-level cities, suggestions about population density, industrial development option, water infrastructure investment, and water management policies will be raised to lead China finish its urbanization process in a more sustainable pattern in the future.
