2014年6—9月采用样线(点)法对宣恩县的鸟类进行调查,根据植被特征划分出农田、居民区、灌丛、湿地和森林5个生境类型,共记录鸟类78种,隶属12目25科,其中属于国家Ⅰ、Ⅱ级重点保护野生鸟类分别有1种、8种,属于中国特有种1种.鸟类群落的α多样性指数(H′)、均匀度指数(J)分别为3.075、0.410;β多样性分析表明:Jaccard相似性系数最高的是农田-居民区,为0.714,最低的是灌丛-湿地,为0.039.人为干扰影响鸟类多样性,提倡建立生态补偿机制.
By the method of line(or points)transect,a bird survey was conducted in Xuan'en,Hubei Province from June-September 2014.Habitats were classified into five catalogues,i.e.farmland,residential areas,thickets,wetlands and forest.A total of 78 bird species was recorded,which belonged to 25 families and 12 orders.Among the bird species recorded,1species was in the Grade Ⅰnational key protected birds and 8species was in the GradeⅡ,1endemic to China.Theαdiversity index(H′),and evenness index(J)were 3.075 and 0.410;Beta diversity analysis showed that:Jaccard similarity coefficient(Cj)farmland-residential area is the highest(0.714),brush-wetlands is the lowest(0.039).Disturbance from human had impacts on the avian diversity.Eco-compensation measures were recommended to practice for better management in Xuan'en.
