| 摘 要： | 根据长荡湖底泥和水体实测资料,分析了底泥的污染及营养物质释放特征,发现底泥释放再悬浮产生的污染负荷占到入湖污染负荷总量的比例分别是:高锰酸盐指数为16%,TN为25%,TP为21%,是引起近年来长荡湖水体富营养化加剧的重要因素,特别是湖西区和湖南区达到富营养水平,湖心区水体含氮磷浓度也较往年有明显增大。为控制长荡湖底泥污染及水体富营养化的加剧,提出了长荡湖水环境保护的相关对策措施。

| Abstract: | Based on analysis of sediment and water samples of Changdang Lake, results showed that pollution load of COD, TN and TP, which were released from sediments, accounted for 16%, 25% and 21% respectively of the total pollution load importing into the Lake. As a result, eutrophic status of the Lake was deteriorating in recent years. The water in west and south part was in eutrophication status, and TN, TP in centre of lake increased obviously. To control eutrophication, some countermeasures were proposed to protect the Lake. |
