河流系统健康体系及评价方法研究

考虑反映河流系统的动力状况、水质状况、河流地貌和生物指标状况、河流服务状况等4个方面，构建了河流系统健康体系。建立了基于模糊理论的河流健康状况多层次评价模型，给出了相应的评价指标、标准和权重。以海河三岔口河段为例，应用已建的河流系统健康状况模糊综合评价模型，对河流系统的健康状况进行了评价。结果表明，该评价体系能定量地从各层次分项指标和总体角度反映河流健康状况，可为河流管理和生态修复工程提供技术支持。

Research on Assessment Methods for River System Health Status

A river health status assessment system is established, which considers river dynamics condition, water quality, river geomorphology & biology index status and service status. According to multi-hierarchical fuzzy theory, the model assessing a river health status is proposed, and the assessment indexes, quantizing standard and weight calculation function are suggested. As an application of the model established, the health status of Sanchakou reach of Haihe River is assessed. The assessment system can reflect the current health status of a river quantitatively, and the assessing results will be convenient to provide technical support for river management and ecological restoration project.
