摘　　要：为分析北疆地区农村饮用水源河道水质现状,对长期监测水质数据进行分析计算,获得河道水质现状、时空特征及富营养化特征。河流水质现状中TP浓度最大为0.46 mg/L,氨氮含量从上游至下游为先增后减变化,全河道上分布为0.77~2.77 mg/L,COD全河道平均值为13.91 mg/L。水质评价参数Q值夏季低于冬季,河道中下游Q值低于上游,随年补水量递进,参数Q值降低。2019年夏季水质营养化参数P值平均为53.5,2020年夏、冬季水质营养化参数P平均值分别为26.5、38.2,局部断面处受较长补水净化周期影响,营养化参数P值较高。论文可为饮用水源河道水质状态分析及富营养化评价提供一定参考。In order to analyze the current water quality of rural drinking water sources in northern Xinjiang,the long-term monitoring water quality data was analyzed and calculated to obtain the water quality,temporal and spatial characteristics and eutrophication characteristics of the river were obtained.The results indicate the maximum TP concentration is 0.46 mg/L,and the ammonia nitrogen content increases firstly and then decreases from the upstream to the downstream,fluctuating between 0.77 and 2.77 mg/L for the entire river,and the average COD of the entire river is 13.91 mg/L.The Q value of the water quality evaluation parameter is lower in summer than that in winter,and the Q value of the middle and lower reaches of the river is lower than that of the upper reaches.In addition,the Q value of the parameter decreases with the annual water replenishment.The average P value of the water quality nutrition parameter in the summer of 2019 is 53.5,and this value in the summer and winter of 2020 is 26.5 and 38.2 respectively.What's more,the longer replenishment and purification cycle will lead to higher the nutrition parameter P value at the local section.The above conclusions can provide a certain reference for the analysis of the water quality status of the drinking water source river and the evaluation of eutrophication.
