摘　　要：根据2014~2016年对化成水库的水质监测,采用综合营养状态指数法和模糊综合评价法对水库富营养化现状进行了评价。结果表明两种评价方法得出的结果一致,该水库在此三年间持续处于中营养状态。对该点位水质富营养化变量指标(COD_(Mn)、NH_3-N、TN和TP)进行特征分析,TN和TP均为Ⅲ类,COD_(Mn)处于Ⅱ—Ⅲ类,NH_3-N达到Ⅱ类。分析该区域水质各指标为NH_3-N和TN污染主要来源是点源污染,而TP和COD_(Mn)主要来自非点源污染。根据分析结果对化成水库富营养化进行成因分析并提出科学建议。Based on the monitoring data of water quality in Huacheng Reservoir during 2014 - 2016, the comprehensive nutrition index assessment and the fuzzy comprehensive evaluation method were used to evaluate the conditions of water quality and eutrophication status. The results indicated that both the two methods get the same result, the reservoir was at medium eutrophication level in the three years. Eutrophic indexes of the water including potassium permanganate index （ CODMn ） , ammonia nitrogen （NH3-N）, total phosphorus （TP） and total nitrogen （TN） were analyzed. The results showed that： TN and TP concentrations belonged to class Ⅲ of national water quality standards, CODMn concentrations were in Ⅱ or Ⅲ class of national water quality standards, NH3 -N concentration were better than the class Ⅱ of national water quality standards. Analysis of each index of water quality in this area showed that NH3 -N and TN were mainly from point source, while TP and CODMn were mainly from non - point source, the cause of the Eutrophication of Huaeheng Reservoir were analyzed and scientific suggestions were put forward.
