摘要
根据2005年浙江省长潭水库水质指标的监测结果，分析了该水库水质指标变化的统计特征值及其相关性。结果表明：水库水质大部分时间都处于I类或Ⅱ类水平。各水质指标全年的变异系数在10％～75％之间。水体pH值与水温呈极显著的正相关，水体中氨氮含量和石油类含量与pH值呈显著的正相关，水体中溶解氧与水温呈显著的负相关。水库富营养生态治理途径有：控制水库周边点源和农业面源污染；治理铅锌矿尾矿污染；修筑人工湿地净化水质；大型水生（湿生）植物的引种及群落优化。
Based on the monthly monitoring data of water quality of Changtan reservoir in Zhejiang province in 2005, the statistical eigenvalue of the variation of water quality indexes and their correlation each other have been analyzed. The results showed that in most parts of the year the water quality belonged to the first class or the second class. The variation coefficient of water quality was 10% -75%. Correlation analysis revealed that there was significantly positive correlation between＇pH- value and water temperature, while there was obviously negative correlation between dissolved oxygen and water temperature. There are many approaches to control eutrophication of Changtan reservoir, including preventing point and non - point source agricultural pollution, controlling lead and zinc pollution from the mine, constructing artificial wetland and introducing aquatic plants, etc.
