摘要
宁夏引黄灌区内湖泊众多,近些年随着环境污染、旅游开发,湖泊水质状况面临威胁。以宁夏引黄灌区重点湖泊为评价对象,利用综合水质标识指数法和综合营养状态指数法,对湖泊水质和富营养状态进行评价分析。结果显示:多数湖泊达到了水环境功能区目标Ⅳ类水标准,水质超标因子主要为TP和TN,但多数湖泊存在轻度或中度的富营养化情况,基于此提出保护对策,为宁夏引黄灌区湖泊水质保护提供决策依据。
There are many lakes in Ningxia Yellow River irrigation area,but in recent years,due to environmental pollution and tourism development,the lake water quality is under threat.In this paper,several key lakes were selected for evaluation,and the water quality and eutrophication status of the lakes were evaluated using comprehensive water quality index method and comprehensive nutrition status index method.Most of the lakes reached the criterion of object IV of the water environment functional area,TP and TN were the main factors higher than the allowed criteria.However,most lakes displayed mild or moderate eutrophication.Countermeasures were put forward to provide a basis for decision-making for lake water quality protection in the Yellow River irrigated areasin Ningxia.
