摘　　要：选取渭河宝鸡市区段5个监测点进行实地采点取样,对CODCr,CODMn,NH3-N,TP 4个水质监测指标做实验分析,利用"中心化"和"均值化"的灰色关联分析法对水样进行评价.结果表明,各主要断面总体水质良好,局部监测点水质存在污染.针对河流的水生态现状,提出改善和恢复水环境,恢复河道的生态功能和自然风貌的河流污水截排、底泥清淤、垃圾管理、生态河堤再造等主要措施,从而为宝鸡市渭河治理与保护及流域建设提供科学依据.Five sampling sites in the major section of Weihe River were selected. and four water quality monitoringindices were experimentally analyzed including CODCr,CODMn,NH3-N,TP. with the method of a＂centralized＂grayrelational analysis and the＂equalized ＂gray analysis. Using＂centralized ＂gray relational analysis and＂equalized ＂gray relational analysis of water samples for evaluation. The results showed that the main section of the overall waterquality is good. There is water pollution in portion of monitoring points. Overviewing the ecological status of riverwater,for improving and restoring water environment and the restoration of river＇s ecological functions and naturalstyle,some major initiatives must be taken for instance,wastewater interception,sediment dredging,wastemanagement,eco-embankment reconstruction and others. The conclusion of the study may provide some basis forthe management and protection of sections of the Weihe River flowing through Baoji City.
