安徽颍州西湖省级湿地自然保护区鸟类多样性

摘要

From June,2013 to June,2015,an investigation of bird communities had been made in habitats of farmland,river wetland and lake wetland in Yingzhou West Lake Reserve.A total of 123 species were recorded,which belong to 14 orders,33 families and 69 genera.We analyzed the relative diversity indices.Results showed that the species number and density in autumn were higher than those in other seasons.The Shannon-Wiener index and Pielou index in summer were the highest.The species number in lake wetland was the greatest among the three habitats.The density,Shannon-Wiener index and Pielou index in lake wetland and farmland were higher than those in river wetland.At the same time,the dominance index in river wetland was the highest.In terms of diversities at family and genus,the G-F index in Yingzhou West Lake Reserve was 0.76.Yingzhou West Lake Reserve is an important stopover and wintering site for shorebirds and Anatidae birds.%2013年6月2015年6月,对安徽颍州西湖省级湿地自然保护区内农田区、河流湿地和湖泊湿地3种典型生境的鸟类进行调查,共记录到鸟类123种,属于14目33科69属.按照季节和生境的不同对鸟类多样性进行分析,结果表明:颍州西湖湿地保护区秋季鸟类的物种数和密度显著高于其他季节,而夏季拥有最高的物种多样性指数和均匀度指数;在颍州西湖湿地保护区3种典型生境中,湖泊湿地的鸟类物种数显著多于河流湿地和农田区,同时,湖泊湿地和农田区鸟类密度、物种多样性指数、均匀度指数显著高于河流湿地,而河流湿地拥有最高的优势度指数.就科属水平上的多样性而言,该保护区鸟类群落科属间多样性为0.76.颍州西湖湿地是鸻鹬类和雁鸭类等迁徙鸟类的重要中途停歇地和越冬地.
