摘　　要：在考虑河流生态健康评价指标层面的基础上,以国内外河流评价指标为依据,以北京市汤河为例,以沿河典型河段所测21个样点的5类因素涉及17个指标为基础,用因子分析法分析各指标对于北京市汤河生态健康评价指标的相关性。结果表明:1)河床作用因子、植被作用因子在头道穴段和汤河口段对汤河总体生态健康影响较大;2)在21个调查河段中,对北京市汤河生态健康起显著影响作用的主要为河流岸坡因子、植被作用因子。研究结果可为汤河(北京段)生态修复提供参考。Considering the ecological health evaluation of river,the Tanghe River in Beijing was taken for a case study of the correlation among the evaluation factors by referencing river-based evaluation study abroad.A total of 17 indicators out from 21 measured samples in 5 categories along the typical river section of Tanghe River were analyzed The results showed that：1） riverbed effect and vegetation have greater impacts on the overall ecological health in the Toudaoxue and Tanghekou sections; 2） the most significant factors affecting ecological health of Tanghe River are bank slope factor and vegetation in the measured river sections.The result of this study might offer ecological restoration reference for the Tanghe River （Beijing segment）.
