Study on the Interactive Intimidating Relation between Urbanization and Environment in Arid Area Based on Grey System Theory

摘要

There are all sorts of contradictions and intimidations between urbanization and environment objectively. The intimidations of urbanization in arid area mainly come from the growth of resource consumption, the aggravation of environmental pollution and the sprawling expansion of urban land. The restrictions of environment mainly come from the resource condition, the environmental capacity and the ecological menace. The case study of He-Xi Corridor shows that the grey relational degrees between urbanization and environment of the industry-oriented cities are high, of the agriculture-oriented cities are low and of the tourism-oriented cities are relatively high. The changing trends of coupling degrees of He-Xi Corridor and the cities are not unanimous with that of urbanization or environment totally. They embody the coupling state changes of urbanization and environment. In order to realize the harmonious development with environment in arid area, urbanization should change its traditional developmental ideas and pay much attention to water resources and environment.
