The Developing Evaluation And Transition Of Resourced-based City In Arid Area

The development of resource-based city is one of the most important issues that people concerned. Because of its particularity, resource-based city was built as resource base and diggings in the early city construction, lacking of the long-term planning and management in future. As time went by, more and more resource-based cities entered into the stage of mature and exhaustion owning to the finity and non-regeneration. Therefore, many problems have been raised in some resource-based cities, and a few resource-based cities have gotten into trouble and serious economic & social conflicts. So it is very necessary to probe into the development and transition of resource-based city from the sustainable development aspect, and to provide resource-based city with some useful reference.Under the direction of sustainable development theory and life-cycle theory, combining the development and transition experience from resource-based cities home and abroad, the thesis builds index system that included resource subsystem, economic subsystem, environmental subsystem and social subsystem. After differentiating and analyzing the notion that related resource-based city and introducing regional background and general situation., the author take Jinchang city, one of the resource-based cities in arid area, as a typical example. First of all, the thesis assesses quantitively the present situation (2003) of Jinchang city by using AHP. Secondly, the thesis assesses quantitively the history development (1981-2003) by using the entropy. Finally, by synthesizing the present and history assessment, analyzing the challenge and opportunity quanlitively that Jinchang city, one of the resource-based cities, encountered, the thesis puts forward the basic ideas and countermeasures of resource-based city's development and transition such as diversified economic structure, water-saving economic development, centralized urban layout and real ecological city.By assessing and analyzing, we can conclude that resource-based cities in arid area have some problems that resource-based city had encountered such assingularity of economic structure and duality management system, however, the grave restriction of water resource and the fragility of environment were two challenges that resource-based city in arid area faced. In addition, it is very difficult for resource-based city to fulfill its transition by itself, so we must ask for the national and regional policy supporting, only in this way can we achieve the transition of resource-based city smoothly.
