南疆资源型城市生态安全评价——以库尔勒市为例

Ecological Security Evaluation of Resource-based Cities in South Xinjiang——A Case Study of Korla City

在新疆资源型城市GDP快速增长的同时,资源枯竭、环境污染越来越成为资源型城市实现可持续发展的瓶颈因素。尤其是以油气为主要资源支持经济发展的城市,因油田的开采、油气运输和利用而引起的环境污染和生态破坏是无法避免的。选择位于新疆中部的库尔勒市为研究对象,运用生态安全评价PSR概念模型构建生态安全指标体系,结合均方差权值法和综合指数评价法,从时间尺度上评价城市生态安全和发展趋势,针对城市生态安全问题提出了调控对策。

With the rapid growth of GDP in resource-based cities of Xinjiang, the resource depletion and environmental pollution have become bottlenecks of the realization of sustainable development in resource-based cities. Environmental pollution and ecological destruction, caused by the exploitation of oil field as well as the transportation and utilization of oil-gas, can＇t be avoided, especially in those cities whose economic development are mainly supported by the oil-gas resources. This paper chose Korla, located in the middle of Xinjiang, as the research object. It made evaluations of urban ecological security and development trends from the time span, using the PSR concept model of ecological security assessment to build the ecological security index system as well as combining with hoth Mean-Squared Deviation Weight Method and Comprehensive Index Evaluation Method, and finally proposed regulation countermeasures for the urban ecological security problems.
