| 摘 要： | 文章研究了含不同浓度悬浮物的水流,在流经由长江中下游典型水生植物风车草、石菖蒲、菱、金鱼藻、轮叶黑藻、亚洲苦草所构建的水生高等植物群落时悬浮固体浓度的变化规律,分析了群落及群落中每种水生高等植物对悬浮固体的去除效果。结果表明,所构建的水生高等植物群落能够有效地降低水体中悬浮固体的浓度,但不同种类的水生高等植物对悬浮固体浓度降低的效果相差很大。

| Abstract: | Rule of concentration change of suspended solid was discussed when water containing suspended solid was flowing through higher aquatic plant community constructed by Cyperus alternifolius,Acorus gramineus,Ceratophyllum demersum, Hydrilla verticillata and Vallisneria spiralis in the middle and lower reaches of the Yangtze River,with analysis of removal efficiency of the community and each kind of aquatic plant.Results showed that the constructed community can effectively reduce suspended solid concentration ... |
