摘　　要：浮游藻类对水质变化敏感,其种群演替监测可作为水环境监测的辅助手段。本研究以沈阳市的3个城市内湖为例,探究我国北方城市内湖浮游藻类的群落演替对水质变化的响应,分析其辅助水环境理化监测的可行性。从3个内湖共观测到7个门51个属的浮游藻,绿藻和硅藻占明显优势。浮游藻类的丰度和优势种属存在明显的季节性变化,丰度在春季最低,秋季达到峰值,具有明显的北方寒冷地区特征。绿藻和硅藻对温度变化敏感,蓝藻的优势度与水质质量的相关性更为显著。基于污染物综合指数和藻类多样性指数辅助水质指标评价,3个被测内湖的水质主要呈中度污染水平。Since planktonic algae are sensitive to water quality,the population diversity analysis is considered as one of supplementary means for water environment monitor.To explore the response of planktonic algae community to the water quality in urban lakes in northern China,and determine the feasibility as a supplementary for physical and chemical monitoring methods in the water environment,three inner urban lakes in Shenyang were selected.A total of 51 genera from 7 phyla were observed from the lakes with Chlorophyta and Bacillariophyta as the dominants.The abundances and dominant species of planktonic algae had seasonal changes,the minimum and maximum were obtained in spring and autumn,belonging to a characteristic of cold areas in the north.Chlorophyta and Bacillariophyta were more sensitive to temperature changes,and the correlation between the dominance of Cyanobacteria and water quality was more significant.The water qualities of three lakes were evaluated in the moderate pollution level based on water quality monitoring combined with pollutant comprehensive index and planktonic algae diversity index.
