摘  要：
分别于2011—2016年对星海湖北域常规监测点和2017年对星海湖整体水域及周边水系补充监测点的水环境进行采样检测分析,并运用综合营养状态指数法进行富营养化评价,全面了解星海湖营养化状态的时空变化规律,并在此基础上分析了富营养化污染成因。结果表明:星海湖近年来的营养化状态有明显恶化趋势,常规监测点水质由2011—2014年的轻度富营养转变为2015—2016年的中度富营养;补充监测点数据显示,星海湖不同水域受污染程度不同,轻度、中度和重度富营养化现象并存。星海湖的主要污染源为渔业养殖、生活污水、黄河补水、山洪水、干湿沉降等,其中渔业养殖和水源输入造成污染的贡献最大。

摘  要：
Based on the collecting data of routine monitoring points in the north region of 2011—2016 and supplementary monitoring points in the whole region of Xinghai Lake and surrounding water regions of 2017,the comprehensive nutrition state index method was used for eutrophication assessment to understand the temporal and spatial variation of the nutrient status of Xinghai Lake. On the basis of the survey data analysis,the causes of eutrophication pollution were analyzed. The results showed that in recent years,the nutrient status of Xinghai Lake had a trend of deterioration,and the water quality of the routine monitoring points had changed from slightly eutrophic in 2011—2014 to moderately eutrophic in 2015—2016. Supplementary monitoring data showed that different water areas of Xinghai Lake were polluted differently,and mild,moderate and severe eutrophication occurring at the same time. The main pollution sources of Xinghai Lake are fishery cultivation,domestic sewage,water recharging in the Yellow River,mountain floods water,dry and wet deposition,among which fishery cultivation and water input contributed most to pollution.
