| 摘 要： | 测定长湖底质有机质及总氮、总磷等指标,通过和其他富营养化湖泊的相关指标或当地环境本底值比较,评价长湖底质对湖水富营养化的潜在贡献,其结论是:有机质平均值为43.84 g/kg,含量丰富;总磷平均值为0.057%,含量较低,但在湖中各点差异明显;湖泊底质含氮量为0.234%,总体偏高;底质有机指数很高,湖泊处在严重的肥污染状态;有机质和营养盐主要来源于藻类等浮游生物;有机碳和总氮的相关性好,具有某种线形关系.

| Abstract: | Analyzeorganic,total nitrogen,total phosphorus and other indicatorsof sediment in Changhu Lake,and compared toother eutrophicationlakes or local environmental value,we evaluate the potential contribution of sediment for eutrophication : rich in organic matter,the average value is 43.84 g/kg.TP content,the average value is 0.057%,is low,but the value is clearlydifferent during different monitoring of the lake;High nitrogen contentin sediment of the lake,the average value is 0.234%;High organic index of the entire lake,the lake is in deep state of fertilizer pollution;Organic matterandnutrients is mainly from the plankton such as algae;organic carbon and nitrogen,with a particular linear,has close relevance. |
