额济纳绿洲水—生态—经济—复合系统可持续定量评估

Quantitative Assessment of Sustainable Development of Compound System of Ejin Oasis Water-ecology-economy

水是干旱区、半干旱区最重要的因子之一.目前,水资源短缺已成为黑河下游额济纳绿洲社会经济发展的主要制约因子,而水的短缺也引发了诸多生态环境问题.本文应用生态经济领域的可持续发展方法对额济纳绿洲水—生态—经济复合系统进行定量评估,其具体方法就是建立指标体系并对其进行综合评价.本文采用灰色关联方法对额济纳绿洲水—生态—经济复合系统的各指标因子进行筛选,建立绿洲复合系统评价指标体系,然后运用可持续发展度对复合系统进行综合评价.

Water is one of the most important factors in arid and half arid districts. At present, water shortage has become a vital restricting factor of the social and economic developments in the downstream of Heihe River, causing a great deal of ecological environment problems. In this paper, the compound system of oasis water-ecology-economy is quantitatively assessed using ecological economic theory and method, its concrete method is to establish the system of indexes and carry on a comprehensive appraisal. By filtering all the indexes of the compound system of oasis water-ecology-economy with grey related method, the evaluation index system for the oasis compound system is established, and the comprehensive appraisal of the compound oasis system is carried out by sustainable developing degree.
