摘要：

为了解底泥中重金属在不同季节的含量变化，笔者连续监测了长寿湖底泥在丰水期、平水期和枯水期中重金属Ni、Cr、Cd、Cu、Pb、Zn含量的变化，并考察了重金属含量的影响因素。结果表明，底泥中重金属含量呈现明显的季节变化特征，其中寿岛底泥中重金属含量的最大值出现在平水期，其他各采样点的最大值均出现在丰水期。此外，还主要研究了pH对底泥中重金属含量的影响，得出重金属含量与pH值有一定的正相关关系。

Abstract:

In order to understand different season variation of heavy metals contents, contents of heavy metals such as Ni, Cr, Cd, Cu, Pb and Zn in sediments of Changshou Lake were monitored continuously through high-water period, normal-water period and low-water period. The influence factors of heavy metals on the contents were also investigated. It was found that heavy metals in the sediment showed obviously seasonal variation characteristics. The maximum of heavy metals in Shoudao, with high level of eutrophication, appeared in normal period. The author also studied mainly that pH influences on the contents of heavy metals in sediments, the conclusion was that contents of heavy metals and pH had a positive correlated relationship.
