摘要
根据洪灾后对苏南滆湖、东太湖、长荡湖的调查和采样测定，分析了洪灾对湖泊水质和生态环境的影响。调查研究结果表明，洪灾使湖泊中悬浮物质大量增加，透明度明显降低，浮游植物大量增加，水草明显减少， ＴＮ、ＴＰ、ＣＯＤＭｎ等明显提高，湖泊的水质总体下降。根据研究结果，还提出了防灾抗灾的建议。
An investigation and a sampling determination are made to Gehu Lake,East Tai Lake and Changdang Lake in South Jiangsu after flood.An an alysis is made on to the effects of the lake water quality and ecological Envir onment caused after flood.The conclusion shows that flood results in the suspend ed matter increasing rapidly,the transparency droppings distinctly,the phytophag ous increasing sharply,the water plants reducing evidently ,and TN、TP、CODM n rising sharply,then the total Lake water quality is decreasing.On the basis of this result,the suggestions of preventing and fighting flood are raised in th is paper.
