军山湖底栖动物种群结构与时空分布
Community Structure and Distribution in Space and Time of Benthic Animals in Junshan Lake
摘要
Abstract
To explore the status of benthic animal communities and distribution in space and time in Jun-shan Lake.A quarterly investigation on benthic animals was conducted in the period from May 2013 to May 2014.27species from 6 classes and 3 phylas in 15 sampling sites were recorded.Corbicula fluminea,Nephtys po-lybranchia,Limnodrilus hoffmeisteri and Tubifex sinicus.were the dominant species in Junshan Lake.The density and species quantity of benthic animals varied largely in the four seasons.The highest density and most species of benthic animals occurred in summer,followed by those in spring and autumn.The minimun was in winter, and the communities were dominated by Mollusca, Oligochaeta, Polychaeta.Diversity analysis indicated that Shannon-Wiener and Margalef in summer were more than in spring and autumn,Shannon-Wiener and Mar-galef in spring and autumn were more than in winter.The number of simpson in summer was smaller than in spring and autumn,the number of simpsor in spring and autumn was smaller than in winter.There was no differ-ence in the number of Pielousb in four seasons.The results suggest that the structure of the benthic animal com-munity in Junshan Lake changes obviously in the four seasons and water environment has impact on the benthic animal communities in Junshan Lake.关键词
