城市化进程中区域水土资源生态风险评价研究
|
摘要
在分析区域生态风险因子的基础上,结合环境、经济、社会三方面内容,构建水土资源耦合生态系统风险评价指标体系。以西安市浐灞生态区为例,采用改进熵权法和加权求和法进行评价研究。评价结果显示,浐灞区水土资源复合开发之前生态风险值为0.512 1,属较高风险,水土资源耦合系统的生态风险值为0.197 7,属低风险。研究结果表明区域水土资源复合开发后,耦合系统的生态风险降低,"经济—社会—生态"系统协调发展,人与自然和谐相处。
Based on the analysis of regional ecological risk factors and in combination of such contents in three aspects as environment,economy and society,the index system of land and water resources coupled ecosystem risk assessment is established in this paper.The improved entropy method and the weighted sum method are used to evaluate the ecological risk of soil and water resources coupled system with ChanBa Ecological District as an example.The evaluation results show that Chan-Ba ecological risk before the development of soil and water resources composite exploitation is 0.512 1,which falls into a higher risk.The ecological risk after the development of soil and water resources composite exploitation is 0.197 7,which falls into a low risk,whereby indicating that after regional soil and water resources composite development,the ecological risk of coupled system is low and that"economic-social-ecological system"develops in coordination so that man and nature are in harmony.
