摘要
根据区域脆弱生态环境现状及特征,在分析脆弱生态环境影响因子的基础上,以甘肃省14个地区(地级市)为评价单元,建立了甘肃省脆弱生态环境定量评价指标体系,并确定了各指标权重值。通过计算生态环境脆弱度进行分级,分区评述了不同脆弱生态环境区主要问题及其成因,为生态环境保护提供科学依据。该项研究对甘肃省社会经济的可持续发展有重要作用。
According to present conditions and characteristics of regional fragile eco-environment and analyses of the factors influencing fragile eco-environment, a quantitative assessment index system for Gansu Province is set up and the weighting value of each index is confirmed. By calculating fragile degree of eco-environment, the major problems and causes in different fragile eco-environment regions are analyzed to provide a scientific gist for protection of eco-environment. The study is helpful to the sustainable development of society and economy in Gansu Province
