摘　　要：我们在龙阳湖布设20个采样点位,于2021年、2022年对龙阳湖开展水质监测。以总氮(TN)、总磷(TP)、高锰酸盐指数(COD_(Mn))、以及叶绿素a(Chla)为研究对象进行水质现状分析,并采用综合营养状态指数评估龙阳湖水体富营养化状态,最后据湖泊现状提出建议,为龙阳湖的污染治理提供合理的建议。数据显示,2021年,龙阳湖TN均值为2.408 mg/L、TP均值为0.180 mg/L、COD_(Mn)均值为4.525 mg/L、Chla均值为0.005 mg/L,2022年,TN均值为2.157 mg/L、TP均值为0.162 mg/L、COD_(Mn)均值为4.810 mg/L、Chla均值为0.006 mg/L,水质均为劣Ⅴ类;各监测点2021年与2022年综合营养状态指数均值分别为51.7493、52.4892,均属于轻度富营养状态。20 sampling sites in Longyang Lake were set up to monitor the water quality of Longyang Lake in 2021 and 2022.Taking total nitrogen(TN),total phosphorus(TP),permanganate index(COD_(Mn))and chlorophyll a(Chla)as the research objects,the water quality status was analyzed,and the comprehensive nutritional status index was used to evaluate the eutrophication state of the water body of Longyang Lake,and suggestions according to the current situation of the lake were put forward,so as to provide a reasonable basis for the pollution control of Longyang Lake.The data showed that in 2021,the average value of TN was 2.408 mg/L,the average value of TP was 0.180 mg/L,the average value of COD_(Mn) was 4.525 mg/L,and the average value of Chla was 0.005 mg/L.In 2022,the average value of TN was 2.157 mg/L,the average value of TP was 0.162 mg/L,the average value of COD_(Mn) was 4.810 mg/L,and the average value of Chla was 0.006 mg/L.The water quality reached the inferior V level,the average comprehensive nutritional status index of each monitoring point in 2021 and 2022 was 51.7493 and 52.4892,which belonged to mild eutrophic status.
