秦岭国家植物园蝴蝶群落结构与多样性

Butterfly community structure and diversity in Qinling National Botanical Garden,China

为了查明秦岭国家植物园蝴蝶资源和多样性状况,本研究选取了5种生境,利用样线法进行了3年的蝴蝶多样性观测。结果表明:秦岭国家植物园蝴蝶共有5科76属134种;物种丰富度指数、物种多样性指数、均匀度指数和优势度指数分别为1.3295、3.4616、0.7068和0.7656;其中蛱蝶科属数及物种数最多(33属65种),凤蝶科最低(5属10种);蛱蝶科物种多样性指数及物种丰富度指数最高,分别为2.8525及1.3622;凤蝶科多样性指数最低(1.4936);粉蝶科物种丰富度指数最低(0.2790)。5种生境中,随着植被丰富度的增加,蝴蝶多样性指数上升。

In order to determine butterfly resources and diversity status of the Qinling National Botanical Garden,we used the transect method across three years to observe butterflies within five habitats.A total of 134 species were recorded,belonging to 5 families and 76 genera.The species richness index,diversity index,evenness index and dominance index were 1.3295,3.4616,0.7068 and 0.7656,respectively,among them,Nymphalidae had the largest number of genera(33)and species(65),while Papilionidae had only 5 genera and 10 species.Nymphalidae had the highest diversity index(2.8525)and richness index(1.3622).Papilionidae had the lowest diversity index(1.4936)and Pieridae had the lowest richness index(0.2790).The comparison of butterfly diversity indicators in different habitats showed that butterfly diversity index increased with the increase of vegetation richness.These results show an abundance of butterfly diversity,indicating that Qinling National Botanical Garden may be of significant conservation value.
