浅谈流域生态环境健康评价

Advanced on assessment of watershed health

对流域进行健康评价,将为流域的规划、管理和保护以及流域综合治理提供决策依据。对国外一些流域进行生态环境健康评价的理论和实践进行了研究。总结了以流域水质评价为核心内容的评价体系、以流域土地利用方式为核心内容的评价体系、压力-状态-响应评价体系、自然条件限制因子-流域生态健康指示因子-人类活动影响因子评价体系、生物因素-非生物因素评价体系和开发与保护并重的流域健康评价体系等6种主要评价体系。

Evaluating the watershed health situation can help watershed layout, watershed management, watershed protection and watershed integrated management and put forward the basis for decision-making. The paper introduces six main evaluation systems of water quality, land use, Pressure-State-Response, natural factor-watershed health indicator factor-human being influence factor, zoetic factor-abiotic factor and paying equal attention to development and protection.
