阿克苏地区夏季4种不同生境鸟类群落调查

2009年7月,作者在阿克苏市周边选择了4种典型的生境,即果园、农田、防护林、荒漠开展鸟类群落多样性调查;同时将涉及的鸟类按食性分为杂食性鸟、食虫鸟、食谷鸟、猛禽4个鸟类食性集团,研究了不同群落捕食集团的组成特点。结果表明:4种不同生境的鸟类可划分为4类群落,其中果园区鸟类群落丰盛度最高,荒漠区鸟类群落丰盛度最低;农田区鸟类群落多样性指数和均匀性指数均最低;而防护林区鸟类群落多样性最高;荒漠区鸟类群落均匀性指数最高。在4种生境中杂食性鸟密度比例最高,而食虫鸟种数比例最高。

Survey of Four Bird Communities with Different Habitats in Summer in Aksu Region

A survey on bird community with different habitats was carried out in Aksu Region in July,2009.Four typical habitats including orchard,farmland,shelter belt and desert were selected to study diversity of bird communities and all bird species were grouped into omnivorous,insectivorous granivorous and predators based on their eating patterns.The results showed that bird species richness of orchard was the greatest,while that of the desert was the lowest.As to bird species diversity and eveness,farmland was the lowest while species diversity of shelter belt was the greatest and,species eveness of desert was the greatest.Among the four habitats,share of density of omnivorous was highest while share of species of insectivorous was the highest.
