摘    要:于2006~2008年对甘肃小陇山林区不同生境类型中蝴蝶多样性进行了调查研究,研究中依据植被的不同将该林区的蝴蝶生境划分为6种类型:人工林、灌木丛和次生林、居民农田、针阔混交林、落叶阔叶林、针叶林。共获得蝴蝶标本5365只,隶属于11科116属210种。计算了6种生境类型中蝶类物种丰富度、相似性系数和多样性指数。不同生境中,灌木丛和次生林蝶类物种的多样性指数、丰富度和个体数量较高,人工林物种多样性指数、丰富度和个体数量较低;人工林与针叶林之间的相似性系数(0.4194)最高,针阔混交林与落叶阔叶林的相似性系数(0.2951)次之,人工林与灌木丛和次生林之间的相似性系数(0.0769)最低,表明各生境之间蝶类相似性系数很低。

关 键 词:小陇山  蝶类  生境类型  多样性

Abstract:The diversity of butterflies in different habitat types in the Xiaolongshan forest area of Gansu Province was surveyed from 2006 to 2008.Six habitat types were classified based on vegetation differences:planted forests,shrub land and secondary forest,inhabited farmland,coniferous-broad leaved forest,broadleaved forest and coniferous forest.A total of 5 365 butterfly specimens were collected and 210 species belonging to 116 genera and 11 families were identified.Species richness,species composition similarity(Jaccard index) and species diversity index(Shannon-Wiener index 'H') were calculated for the six habitat types.The species diversity index,species richness and butterfly abundance were highest in shrub land and secondary forests and lowest in planted forests.Species composition was most similar between planted forest and coniferous forest(Jaccard index = 0.4194),then coniferous-broadleaved forest and broadleaved forest(Jaccard index = 0.2951) with planted forest and shrub land and secondary forest having the least species similarity(Jaccard index = 0.0769).The similarity coefficient of butterfly species was very low in different habitats.
Keywords:Xiaolongshan  butterfly  habitat type  diversity
