摘要
为有效控制表层底泥的有机污染,防止其向水体释放过多的营养元素,通过对南四湖29个采样点中表层底泥样品与上覆水样品的TN、TP和TOC等营养元素的含量测试,分析了在表层底泥中的分布特征及与C/N的相关性,采用SPSS软件做了相关性分析,并利用有机指数对南四湖底泥的环境状况进行评定。结果表明,南四湖已明显有营养元素积累的污染,应采取相应的治理措施以控制进一步污染。
In order to effectively control organic pollution of surface sediment and prevent overfull nutrients from releasing water body, the distributioa character of surface sediment and the C/N correlations are analyzed by testing the total N, P and organic carbon content of 29 surface sediment samples in Nansihu Lake. And then the correlation among the TN, TP and TOC is analyzed with SPSS software. Finally, the organic index is used to evaluate the sediment environment status of Nansihu Lake. The result shows that Nansihu Lake has obvious pollution of nutrients accumulation. Therefore, we must take measures promptly to control the further pollution of the nutrients.
