摘要
根据泾川县的生态环境实际状况,采用DPSIR模型方法,将生态县考核的经济发展、生态环境、社会进步的23项指标分为5层作为生态环境可持续发展综合评价指标体系,同时采用改进的熵权法确定指标权重,计算可持续发展综合指数.结果表明,泾川县的生态环境可持续发展指数从2002年的0.194上升到2011年的0.834,从不可持续状态发展成强可持续状态,这为泾川县国家级生态县的创建打下了坚实的基础.近10年的生态环境可持续情况可以分为两个阶段,即平稳上升阶段和快速上升阶段.
According to the actual situation of Jingchuan ecological environment, this paper use DPSIR model to assess county economic with the ecological environment comprehensive evaluation index system, which including 23 indexes concerned economic development, ecological environment and social progress into 5 layers. In order to calculate the comprehensive index of sustainable development, this paper determined the index weight by using the improved entropy method. The analysis shows that： county ecological environment sustainable development index rose from0. 194 in 2002 to 0. 834 in 2011, from unsustainable state developed into strong sustainable state, Jingehuan national ecological county was created to lay a solid foundation; ecological environment sustainable situation can be divided into two stages, rise smoothly and rapidly risin stage stage for nearly 10 years.
