太湖流域水生态环境功能分区管理绩效评估研究

Performance Evaluation of Water Ecological Environment Function Zone Management in Taihu Basin

目前太湖流域水生态功能分区管理的绩效评估体系尚未建立,无法准确掌握分区管理体系的实施现状、把握影响太湖流域生态系统健康的关键影响因子。以太湖流域水生态环境功能分区为研究对象,基于“压力-状态-响应”模型构建不同时空尺度和管理边界下的绩效评估指标体系,实现了水生态环境功能分区不同管理目标下的差异化绩效评估。

The performance evaluation system for the water ecological function zoning management of Taihu Basin has not been established yet.Therefore,we can hardly give an accurate evaluation of the zoning management system implementation status and the key impact factors that affect the ecosystem health of Taihu Basin.Based on the"pressure-state-response"model,we constructed the performance evaluation index system with different spatial and temporal scales and management boundaries.Differentiated performance evaluation was then conducted under different management objectives of water eco-environmental functional zoning in Taihu Basin.
