摘要
河岸植被是河流生态系统的重要组成部分,在维持河流生态系统完整性和河岸生物多样性保护方面具有重要作用。目前,水电开发影响下河岸植被的物种组成、多样性、种间关联等几方面日益受到关注,是河流生态学研究中的重要热点。文章阐述了水电开发后河流水文、河岸生境、繁殖体扩散、外来物种入侵等影响下河岸植被的响应机制。探讨了河岸植被与生态环境的相关性,提出了今后河岸植被与水电开发相互作用机制,及水电开发的正负生态效应综合影响研究。
Riparian vegetation is an important part of river ecosystem, which plays an important role in maintaining river ecosystem integrality and protecting riparian biodiversity. Nowadays, species composition, diversity and interspecific relation of riparian vegetation under the influence of hydroelectric exploitation have attracted more and more attention, which becomes the new research focus in river ecology. This paper discusses the relation between riparian and ecological environment, and puts forward the research on the interaction mechanism of riparian vegetation with hydropower, as well as the positive and negative of hydropower development.
