大庆市主要湖泊夏季藻类植物多样性及水质评价

摘要

Samples of algae communities in thirty-five lakes in Daqing were collected in June-July 2010. A total of 203 taxa were identified, in which Bacillariophyta and Chlorophyta were dominant. Water quality of urban lakes in Daqing was assessed in terms of Shannon-Wiener diversity index, Pielou evenness index and Margalef index. Result shows that the urban lakes in Daqing are moderately to heavily polluted.%2010年6-8月份对大庆市35个湖泊藻类植物进行采样调查,经显微镜鉴定,共鉴定出藻类植物203个分类单位,藻类植物组成以绿藻、硅藻为主.在调查基础上,利用Shannon - Wiener多样性指数(H')、Pielou均匀度指数(J)、Margalef等指数对各湖泊水质进行初步评价,结果显示:大庆市主要湖泊水质处于中—重度污染状态.
