浙江省峡谷型饮用水水库蓝藻水华的形成机理及对策
首发时间:2009-04-03
摘要:近年来,作为重要水源地的湖泊、水库接连遭受污染,蓝藻水华频繁暴发。湖南镇水库作为浙江省第三大水库,是衢州市重要的饮用水源和工农业用水的主水源。它在促进周围经济发展,保障社会稳定方面发挥了和继续发挥着十分重要的作用。2007年6月中旬起,衢州市乌溪江湖南镇水库水质持续超标,水面出现蓝藻,到6月下旬,蓝藻最大发生面积约1万亩,平均深度约50厘米。湖南镇水库是一座典型的峡谷型饮用水水库,其蓝藻暴发的形成机理与其富营养化状态、独特的地理条件、水文条件和生态系统结构密切相关。本文就湖南镇水库发生“水华”富营养化的现象的形成机理进行深入的探讨,并对治理对策提出意见。

The formation mechanism of algal Canyon drinking water reservoir in Zhejiang province and Countermeasures
Abstract:In recent years, as an important water source ,the lakes and reservoirs is serously contaminated, and frequently outbreaks algae bloom. Hunanzhen reservoir, which is the third largest reservoir in Zhejiang, are important drinking water source and the main industrial and agricultural water sources.營t continues to play an important role in promoting economic development, and ensuring social stability. In mid-June 2007, Hunanzhen reservoir which is in wuxijiang ,quzhou city, continued over water quality standard,and the water appears blue green alga. To late June, algae bloom occurred in an area of about cyanobacteria 1 million Ha, an average depth of about 50 cm.燞unanzhen Reservoir is a typical type of Canyon drinking water reservoirs,燭he formation mechanism of algae bloom is closely related to the status of eutrophication, the unique geographical conditions, hydrological conditions and ecosystem structure.營n this paper, we furtherly?discussed the formation mechanism of \"water bloom\" phenomenon of eutrophication in Hunanzhen reservoir and put forward countermeasures.
