摘  要:
附着藻类是淡水生态系统初级生产者的主要组成部分,对淡水生态系统营养盐循环及沉水植物分布具有重要的影响。本文对近年来淡水湖泊生态系统中附着藻类群落组成、生态功能以及主要影响因子进行了分析,从附着藻类种群结构入手,指出附着藻类通过改变群落中优势种的组成来适应不同的环境,阐述了附着藻类在湖泊生态系统营养盐循环中的作用及其与沉水植物之间的关系。针对淡水湖泊富营养化问题,提出了今后附着藻类生态学研究应侧重于:主要因子(如弱光、高浓度的营养盐等)的交互作用对附着藻类的影响,原位实验方法弄清楚附着藻类在湖泊生态系统碳、氮、磷生物地球化学循环中的作用,以及富营养湖泊附植藻类与沉水植物相互作用的机理。

摘  要:
Periphytic algae are the major component of primary producer in freshwater ecosystems,and play an important role in nutrient cycling and distribution of submerged macrophytes.Based on the previous studies in periphytic algae ecology,we elucidated the community composition,ecological function and their main affecting factors,pointed out that periphyton algae could adapt to various environmental conditions by changing the composition of dominant species in the community,and elaborated the role of periphytic algae in nutrient cycling and the interaction between periphytic algae and submerged macrophyte. With regard to lake eutrophication,the future research topics about freshwater periphytic algal ecology include: interaction effects of main factors such as weak light and high concentration of nutrients on periphytic algae,the role of epiphytic algae in the biogeochemical cycling of carbon,nitrogen and phosphorus in lakes by in-situ experiments,and the mechanism of the interaction between periphytic algae and submerged macrophyte in the eutrophic lakes.
