摘要
消落带是水域生态系统与陆地生态系统的交替控制地带,具有生物的多样性、人类活动的频繁性和生态系统的脆弱性等特征。水位变化是影响湖泊特别是湖泊消落带生态系统主导因素,水位变化的频度、大小、持续时间等因素对消落带水-陆交换过程有重要的影响。本文回顾了近年来水位变化影响研究的基本概况,分析了水位变化对消落带物理因子、植物、动物、生物地球化学过程的影响,并讨论了国内外的研究趋势以及存在的问题。
The riparian zone is an ecotone between the aquatic ecosystem and the terrestrial ecosystem,which is characterized as biodiversity,frequent human activities and vulnerability.Water level fluctuations,especially their extent,frequency and duration,are the main factors affecting the ecosystem of lake/reservoir.This paper summarizes the results of current research on the effects of water level fluctuations on lake/reservoir riparian zone,analyzes the effects that affect the flora and fauna and biogeochemical processes in riparian zones,and discusses the research trend and existing problems in this field both at home and aboard.
