浮游藻类淡水生态环境评价应用现状

Application Status of Planktonic Algae in Evaluating the Freshwater Environment

结合浮游藻类在淡水生态环境中的指示作用,介绍了浮游藻类在指示淡水生态环境特征、水体富营养化及重金属污染监测及评价作用的应用研究,阐明了建立浮游藻类生物监测体系对开展淡水生态系统评价的重要性。指出监测评价过程中面临的物理生境和生态链间的问题,从空间水文、水动力、水生植被、鱼类及藻间等方面系统综述了其对浮游藻类评价作用的影响,展望今后研究方向,以期为中国利用浮游藻类展开淡水环境评价提供理论指导。

In light of its indicating function in the freshwater environment,this paper introduces the applied research of planktonic algae in respects of indicating freshwater environment,monitoring and evaluating the eutrophication and heavy mental pollution of water body,elaborates the significance of establishing a biological monitoring system of planktonic algae on evaluating freshwater ecosystem,shows the problems in terms of physical habitat and ecological chain encountered in the monitoring and evaluating progress,discusses their influence on planktonic algae evaluation from the view of space hydrology,hydrodynamic force,aquatic vegetation,fishes,and algae,as well as proposes the future study of the related fields in hope to serve as the guideline of freshwater environment evaluation concerning planktonic algae in China.
