摘　　要：2016年7月—12月对神龙湖开展了水质调查,并采用综合营养状态指数和内梅罗指数对神龙湖的水环境质量进行评价。结果表明,监测期间TN和TP平均质量浓度分别为1.71mg/L和0.07 mg/L,分别是GB 3838—2002Ⅲ类标准的1.71倍和1.4倍。富营养化状态为中营养,各营养指标对富营养化贡献依次为TP>TN>SD>chla>CODMn。重金属指标内梅罗指数评价结果为轻度污染,重金属污染较轻。The investigation of water quality in Shenlong lake was carried out between July and December, 2016. Comprehensive nutritive index and Nemerow index methods were applied to evaluate the water environmental quality in Shenlong lake. The results showed that TN and TP concentrations during the monitoring period were 1.71 mg/L and 0.07 mg/L on average, which were 1.71 times and 1.4 times of these in GB 3838-2002 Class H standard, respectively. The eutrop-hication status of Shenlong lake was mesotropher. The order of nutritional indexes for lake eutrop-hication was TP, TN, SD, chla, CODMn. The heavy metal indexes evaluated by Nemerow index were mild contamination and the heavy metal pollution situation was lighter.
