多元因子分析模型在河流健康评价中的应用——以苏子河水质特性研究为例

为顺应河流生态可持续发展,提出健康河流、生命河流等概念,维持河流生态系统健康已经成为流域综合管理的必然趋势。综合运用水文学、水力学、泥沙地貌学和水生生态学的基本理论和方法研究河流生态健康的表征因子,确定各因子的阈值,建立流域性水体水质可续发展评价体系。以河流可持续发展为基础,引用代表性的相关指标进行筛选,对流域水质指标进行数值化分析,以苏子河流域水质特性为研究对象,选取出评估河流健康状况的环境因子,客观反映出中小河流域健康状况,为河流的可持续管理和生态环境建设提供参考。

River Health Assessment Based on Multi-factor Model:A Case Study on Water Quality of Suzi River

To maintain the health of river's eco-system has become an inevitable tendency of basin management.In this research,an assessment system for the sustainable development of basin water quality was established according to hydrologic,hydraulic,sediment geomorphology,and aquatic ecological factors.Typical indexes of basin water quality were selected and analyzed using multiple environmental factors analysis.Suzi river watershed was taken as a case study.Environmental factors which reflect the river health state were selected.This research could be a ref-erence for the sustainable management and eco-environmental construction of the river.
