| 摘 要： | 研究了１９９２－１９９４年女山湖大面积围栏养蟹利用与保护沉水植物资源的效果结果表明：围栏内河蟹的食物组成中，主要有菹草、苦草、金鱼藻、马来眼子菜、黄丝草和黑藻等沉水植物．其中菹草、黑藻的出现频率和概念生物量，分别在４、６、７、８和９月为最高；围栏内沉水植物的种类和生物量的变化与河蟹的放养密度关系密切，当河蟹的放养密度不超过３０只·ｈｍ~（－２）时，围栏内沉水植物的生物量与对照组均有明显的增加趋势，由此可证，女山湖大面积的围栏养蟹和适宜的放养密度，有效地利用和保护了围栏区内的沉水植物资源

| Abstract: | A great amount of sediment and organic matter are involved in Taihu Lake, which deieoriates the water quality of river and lake, ence of organic pollutants on Taihu Lake water quality quantitatively, a mathematical model is proposed to simulate ihe loss processes and total amount of runoff, erosion and organic matter in typical years, in which two land use conditions of paddy field and dry land are considered.The result shows that the amounts of soil erosion and organic matter loss increase with surface drainage intensity exponentially, and organic matter content in surface runoff increases obviously during storm period.The problem must be highly thought of and some measures reducing the organic pollution should be taken in the water quality planning and management of Taihu Lake besin |
