区域环境可持续发展度的评价体系及计算——以榆林市为例

在前人研究基础上,给出了建立区域环境可持续发展评价体系的总体结构和设计原则,认为研究应以区域作为地域单元,把区域可持续发展系统分为经济、资源-环境、人口-社会三个子系统.接着从"社会-经济-生态"协调发展、强调以人为本、强调能力建设、可操作性等原则出发,以位于陕北黄土高原中心的榆林市为例,构建出了区域环境可持续度的评价指标,并从水平度、潜力度、协调发展度三个方面定量计算了榆林环境可持续发展度.从计算结果和动态演变来看,到目前为止榆林社会经济是非可持续发展,但由于循环经济理念和环保意识的贯彻,预计2005年以后将有所改善,预测到2010年,榆林社会经济可实现初步可持续发展,到2015年,基本实现城市人口、资源、环境与经济可持续发展.最后提出了未来实现可持续发展的对策.

Research on evaluation system and calculating methods of regional environmental sustainable degree——A case study of Yulin

This paper try to construct a regional composite evaluating index system based on the adaptive capability responding to climate change from the view of sustainable development.The recent research of sustainable development focuses on theoretic and realization approaches;there still is no unified sustainable indexes system that linked them together,so this work has clear practical meaning.Based on literatures about sustainable index system,this paper divides the system into three sub-systems by taking region as regional unit,e.g.economic sub-system,resources-environmental sub-system and socio-population sub-system.Based on some principles,such as harmonious development between eco-environmental and socioeconomic situation,capacity building,maneuverability and so on, it constructs evaluation indices system of regional environmental sustainable degree of Yulin City that is background of this research.Moreover,the hierarchical analytic method is applied to analyze the environmental sustainable degree in three parts,which are level degree,potential degree and coordinated development degree.According to the quantificational environmental sustainable degree and its dynamic evolution,it shows that development of Yulin City is unsustainable up to now.It also predicts that it will attain primary sustainable development till 2010 and essential sustainable development till 2015 since the carrying out of cycling economic ideas and awareness of environmental protection.Finally,some countermeasures are given to realize these goals.
