摘　　要：以2014年黄金河生态养殖区水质监测资料为依据,选择具有代表性的9种监测指标,采用内梅罗污染指数法和综合营养指数法分别对水质状况和富营养化程度进行分析和评价,得出黄金河生态养殖区水质评价等级和富营养化程度。研究结果表明,黄金河生态养殖水域为Ⅴ类水质,各项监测指标均超过长江上游背景水质;综合营养指数在45.9~50.4之间,富营养化程度为中营养,L3断面为轻度富营养化;养殖区域内L2、L3和L4断面水质最差,表明生态养殖对养殖区域内水质存在一定的影响。研究结果可作为三峡库区支流回水区水产养殖规划的参考依据,为合理开发利用三峡库区渔业养殖资源提供科学依据。Based on the monitoring data of water quality in the ecological fishing breeding area in Huangjin River in 2014, this paper selects nine representative monitoring indicators and analyzes the water quality and eutrophication extent with the Nemerow pollution index method and the comprehensive nutrition index method. Research findings showed that the water quality in the ecological fishing breeding area in Huangjin River was Class V with all the monitoring indicators worse than the baseline water quality in the upper reaches of Yangtze River; the comprehensive nutrition index is between 45.9 -50.4, and the eutrophication level is medium, although for the L3 section, eutrophication level is mild; the water quality of L2 , L3 and L4 section in the breeding area are the worst, showing that the water quality are affected by ecological breeding to some extent. The research findings can be used as a basis for aquaculture planning and provide useful data for the exploration of fishery resources in the Three Gorges Reservoir Area.
