【摘要】 2008年5月-2009年4月对西北农林科技大学校园5种生境(阔叶林、针叶林、针阔混交林、疏林灌丛群落、草坪)的鸟类组成进行调查,共记录鸟类51种,隶属9目22科。其中,留鸟35种,夏候鸟15种,旅鸟1种。在鸟类区系类型上,古北界24种,东洋界15种,广布种12种。对不同生境鸟类多样性的分析结果表明:①阔叶林鸟类多样性指数(H=2.9632)和均匀度指数(J=0.7979)最高,草坪鸟类多样性指数(H=0.7889)和均匀度指数(J=0.3175)最低;②阔叶林和针阔混交林的相似性指数(Cs=0.7945)最高,草坪与针阔混交林的相似性(Cs=0.3182)最低。更多还原

【Abstract】 The species of bird in five habitats,including deciduous forest,coniferous forest,mixed forest,open forest and shrub communities,and turf,were investigated from May in 2008 to June in 2009 in campus of Northwest A&F University.Fifty-one species belonging to 22 families and 9 orders were recorded.There were 35 residents,15 summer migrants and one travelers.There were 24 Palaearctic species,15 oriental species and 12 widespread species.The bird diversity analysis of different habitats showed that the highest diversity of the bird community(2.9632)and equitability(0.7979)was found in the deciduous forest,and the lowest diversity(0.7889)and equitability(0.3175)in the turf.The highest similarity of bird community was detected between the deciduous forest and the mixed forest(0.7945),and the lowest between the turf and the mixed forest(0.3182).更多还原
