摘要
本文采用季节性Kendall检验法,分析检验了近5年来淀山湖6个代表断面6项水质监测项目的浓度变化趋势。分析结果显示,溶解氧的浓度呈上升趋势,表明水体自净能力增强;其余各项水质监测项目均呈下降趋势和无明显升降趋势。淀山湖水质参数浓度变化趋势以下降和无明显变化为主,表明淀山湖的水环境状况逐渐好转,水体富营养化有所改善。
The seasonal Kendall test method was used to analyze the concentration trends of six water quality monitoring projects in six representative sections of Dianshan Lake in the past five years. The analysis results show that the concentration of dissolved oxygen is on the rise, indicating that the self-purification ability of the water body is enhanced;the other water quality monitoring items are showing a downward trend and no obvious rising and falling trend. The variation trend of water quality parameter concentration in Dianshan Lake was mainly decreased and no significant change, which indicated that the water environment of Dianshan Lake gradually improved and the eutrophication of water was improved.
