摘　　要：于2006—2008年采用样线法对涪陵区夏季鸟类进行了调查。按照生境特征将调查地划分为水域、次生林、居民点、农田4种鸟类群落。结果表明,共记录到鸟类61种,重要值高的鸟类(200≤重要值≤300)4种,广布型鸟类18种。次生林鸟类群落的物种数最高,而农田鸟类群落的Shannon-Wiener指数最高;农田、次生林—居民点、水域—农田鸟类群落的均匀性指数(Pielou指数)、Jaccard相似性指数、Pearson相关系数分别最高。食物是影响鸟类分布的重要因子。对涪陵区夏季鸟类资源及区域生态保护提出了建议。By the method of line transect,a bird survey was conducted in Fuling District of Chongqing in summer from 2006 to 2008.According to the habitat characteristics,the avian communities were classified into four catalogues,namely water area community,secondary forest community,residential area community and farmland community.A total of 61 bird species were recorded,including 4 species with important value from 200 to 300 and 18 widely distributed ones.The secondary forest habitat had the highest species richness,and the farmland habitat had the highest Shannon-Wiener index.Avian communities of the farmland,forest-residential area and water area-farmland had the highest Pielou index,Jaccard index,and Pearson index respectively.Food is the key factor that affects the distribution of aves.Some countermeasures were put forward in terms of protection of avian resources in summer and regional ecological protection in Fuling.
