摘要
[目的]评价邛海水质富营养化状态。[方法]利用2010年邛海4个监测点数据,运用模糊数学模型,计算其水质营养级别。[结果]青龙寺、二水厂和邛海公园监测点水质属中营养化状态,海河口水质较差,呈中-富营养状态。[讨论]水土流失、农业施肥、包括防水和渔业养殖是导致邛海水质富营养化的主要原因。针对这些因素提出合理化治理对策。
[Objective] The uim was to evaluate the eutrophication of Qionghai Lake.[Method] Used the date of 4 monitoring sites in Qionghai in 2010,the nutritional level of water quality was calaulated by using fuzzy mathematical model.[Result] The results showed that the water in Qinglong temple,the Second Waterworks and Qionghai Park are in mesotrophic state;and in Haihe estuary,water quality is worse than others,it was in meso-wealthytrophic state.[Discussion] Soil erosion,agricultural fertilizer,sewage and fish farming were reasons which led the Qionghai Lake water to eutrophication.
