摘　　要：通过采用凤眼莲净化含银废水 ,定性定量分析了其根系生态系统的组成 .证实凤眼莲水下根系上栖息着大量藻类、细菌、微型动物 ,它们协同作用 ,致使废水中的含银物质、悬浮物、营养盐和有机物发生不同形式的迁移和转化 ;证明了“有机质—细菌—微型动物”食物链在根系的形成及其含银物质的富集 ,是凤眼莲根系生态系统对污染水体综合净化和资源化的基础 .By using Eichhornia crassipes to treat silver containing wasterwater,we quantitatively and qualitatively analysed the components of its ecosystem,verified that the cooperation of a large number of algae, germ and minianimals,which were resting on the root,led to the different form migrations and concertions of silver containing materials,suspended matter,nutrition salt and organic compounds in the wastewater. It was proved that the formation of the 'organic matter bacterium animalcule'food chain in root system and the gathering of silver containing materials were the basis of the synthetical purification and materialization of the Eichhornia crassipes root ecosystem.
