摘　　要：[目的]评价浑河流域水生态健康状况。[方法]运用包含物理、化学、生物3个层面的评价体系对浑河流域沈阳段及抚顺段共12个断面进行生态健康评价,评价体系包括3项1级指标12项2级指标。[结果]健康的断面有天湖大桥、新立堡大桥及长青桥,生态健康状况最差的是沈抚灌渠(入浑河),其余8个断面均为亚健康状态。浑河抚顺段处于健康断面的比例仅占23%,亚健康的断面比例为67%,而沈阳段的健康断面比例则为33%,可见浑河流域沈阳段的生态治理效果较明显,而抚顺段的治理亟待加强。[结论]今后应科学、系统地强化对浑河流域的管理,减少污染物排放,恢复河流两岸植被,减少人为干扰。[ Objective] To evaluate water ecological health of Hun River Basin. [ Method] The ecological health evaluation was carried out on 12 sections of Hunhe River Basin in Shenyang and Fushun parts by including physical, chemical and biological aspects of the 3 evaluation sys- tem, the evaluation system included 3 first level indicators, 12 two indicators. [ Result] The results showed that the Fushun Tianhu Bridge, Xinlipu Bridge and Evergreen Bridge of Shenyang were healthy sections. The worst section was Shenfu irrigation channel. The others were subhealth sections. The percentage of health section in Fushun part was 23% , sub-health cross-section was 67%. The healthy section in Shenyang part was 33% which was higher than in Fushun part. This was the effect of ecological administration by Shenyang government, The ecological management should be laying more stress to improve the river health in Fushun part. [ Conclusion] It is necessary to strengthen the ecological management of the Hunhe River Basin scientifically and systematically, such as to control pollutants, to restore vegetation on river banks and to reduce human disturbance.
