摘要
泥沙是影响河流生态环境的主要因素之一,其生态环境效应对维持水环境平衡和水生生物多样性发挥重要作用.宽级配泥沙是山区河流河床组成的主要类型,与平原河流级配较窄的泥沙相比具有独特的生态环境效应.加之山区河流中大规模梯级水库建设运行等人类活动愈加强烈,宽级配泥沙的生态环境效应问题进一步复杂化.系统梳理了山区河流宽级配泥沙在污染物吸附、解吸和输移等方面的环境效应,以及对水生微生物、动植物的生态效应,分析了梯级水库影响下山区河流宽级配泥沙的生态环境效应变化,探讨了目前研究中存在的问题,并对研究前景进行展望,以期为山区河流生态环境保护提供参考.
Abstract
Sediment is one of the main factors affecting river ecology and environment,playing an important role in maintaining water environment balance and aquatic biodiversity.As the main type of sediment in mountain rivers,wide gradation sediment has unique ecological and environmental effects compared with narrow gradation sediment in plain rivers.With the intensified human activities such as the construction and operation of large cascade reservoirs in mountain rivers,the eco-environmental effects of wide gradation sediment become more complicated.This paper systematically reviews the environmental effects of wide gradation sediment on pollutant adsorption,desorption and transport in mountain rivers,as well as its ecological effects on aquatic microorganisms,animals and plants.And the changes in eco-environmental effects of wide gradation sediment due to cascade reservoirs construction are also analyzed.Then the existing problems in current researches and future research directions are discussed.Therefore,reference for ecological environment protection in mountain rivers can be provided.
