水生植物、水流及底泥再悬浮耦合影响规律研究进展

Research Advances of the Interaction among Macrophytes, Water Flow and Sediment Resuspension

完整的水体概念包括上覆水、底泥以及水生植物等各种环境条件,水生植物、水流和底泥再悬浮之间的相互影响规律是水体生态环境的重要耦合演变过程。从水生植物对水流的影响、水流对水生植物的影响、水生植物对底泥再悬浮的影响3个方面,分析了水生植物、水流及底泥再悬浮耦合影响规律方面的研究进展及需要进一步研究的内容,包括:①基于人工模拟水生植物影响下的水流特性研究成果较丰富,而天然水生植物生物形态特性与水流、底泥再悬浮之间的定量影响研究尚需深入开展;②常规或极端水文事件影响下的水生植物生长繁殖过程与水流、底泥再悬浮之间的定量影响研究成果较少;③多种天然水生植物群落生物特性与水流、底泥再悬浮之间的定量影响研究尚有待推进。

The complete concept of water body includes surface water, bottom sediment, and other environmental conditions such as macrophytes. The interaction among macrophytes, water flow and sediment resuspension is an important process of water coo-environment＇ s coupling evolution. In the present paper, the research advances and some topics requiring further research in these aspects are concluded as follows： ①there are rich reports on the flow characteristics influenced by artificial macrophytes, but quantitative research on the interaction among natural mac- rophytes, water flow and sediment resuspension is required; ②quantitative research findings on the interaction a- mong macrophyte growth under conventional or extreme hydrological events, water flow and sediment resuspension are inadequate; ③quantitative research on the interaction among natural macrophyte communities, water flow and sediment resuspension remains to be promoted.
