呼伦贝尔市水环境承载力评价指标体系研究

Evaluation indicators system of water environmental carrying capacity in Hulunbuir

基于DPSIR模型,综合考虑呼伦贝尔市社会经济和水质状况,选取了21项指标构建了呼伦贝尔市水环境承载力评价指标体系。运用层次分析法理论,计算得到水环境承载力指标体系权重。评价指标体系中,状态和影响子系统对水环境承载力影响显著,其次为响应子系统,驱动力和压力子系统影响较小。

In consideration of the social economy and the water quality of Hulunbuir,21indicators were selected to set up the water environmental carrying capacity evaluation index system based on DPSIR model.The index weight was defined according the analytic hierarchy process.In evaluation index system,status subsystem and impact subsystem were the most significant influence than theother subsystems,followed by response subsystem,and the least influenced were drive subsystem and pressure subsystem.
