摘　　要：对陕西子午岭国家级自然保护区鳞翅目昆虫蝶类资源调查,共记录蝴蝶1926只,隶属于6科34属47种,蛱蝶科种类最多,有13属18种,其次为粉蝶科6属11种,弄蝶科种类最少,有2属3种。在选取的林地、灌丛、湿地、草地和农田5种生境中,林地蝶类物种数量、多样性指数、均匀度及丰富度指数均最高,原因为林地植被类型多,人为干扰小,故恢复植被是提升蝶类资源丰富度的重要手段;蝶类群落结构及多样性随季节的变化而变化,各月份蝶类多样性指数和丰富度指数变化基本一致,从5月份到7月份逐渐递增,到8月份开始下降,9月份达到最低,蝶类种类和数量最多集中在6月、7月和8月。Through the survey of Lepidoptera in Ziwuling National Nature Reserve in Shaanxi Province,1926 butterflies were recorded in 6 families,34 genera and 47 species.Nymphalidae had the most species of 13 genera and 18 species.The second was Pieridae with 6 genera and 11 species.The last was Hesperiidae with 2 genera and 3 species.Among the five selected habitats of woodland,irrigation,wetland,grassland and farmland,the number,diversity index,uniformity and richness index were the highest in woodland due to the large number of vegetation types and less human disturbance.Therefore,restoring vegetation is important to improve butterfly diversity.The butterfly community structure and diversity change along with the seasons as diversity index and richness index see almost the same change,increasing from May to July,then decreasing in August and hitting the lowest point in September.June,July and August see the largest number and most species of butterfly.
