【摘要】 2004年至2006年间分冬夏两季对南京江心洲四种典型生境(居民区、农田区、林区及湿地区)的鸟类资源进行了调查.共记录鸟类67种,隶属10目25科.对冬夏两季不同生境中鸟类群落的密度、现存生物量、多样性指数、均匀度、优势度的对比研究表明,冬季鸟类密度、物种多样性和均匀度均高于夏季,而优势度、现存生物量则夏季高于冬季.在不同生境中,林区鸟类密度、多样性指数最高;居民区优势度最高;均匀度指数冬季林区最高,夏季居民区最高.更多还原

【Abstract】 In the summer and winter of 2004 and 2006,four typical avian communities(residential land,cultivated land,forestland,and wetland) were studied in Jiangxinzhou Alluvium.A total of 67 species belonging to 25 families out of 10 orders were recorded.The results based on the research of the principles of the avian community such as avian density(D),biomass(EB),Shannon-wiener index(H′),species evenness(J) and superiority(C) showed that the density,diversity and evenness of the winter avian community were higher than those of the summer community,but the superiority and the biomass of the former were lower than those of the latter.Different cases were found in different habitats: the highest avian density and diversity occurred in forestland,the highest superiority in residential land,the highest evenness in forestland in winter,but the highest evenness in residential land in summer.更多还原
