| 摘 要： | 2000-2002年调查了河西走廊北山山地蝶类区系组成,共采集蝶类近700只 ,分别隶属6科、25属、30种.研究了蝶类生态分布特征及群落多样性,计算分析了不同生境、不同海拔蝶类群落的丰富度、多样性指数、种间相遇机率、优势度.结果表明,蝶类的生态分布主要受干旱气候影响,不同生境蝶类群落物种多样性指数由荒漠草原＞山地林区＞绿洲农田＞荒漠地带＞高山草甸依次递减.随海拔由低到高,蝶类群落多样性降低.

| Abstract: | In this paper, the faunal composition of butterflies in different habitat types in the north mountainous region of Hexi corridor was surveyed from 2000 to 2002. The collected butterflies total number of was more than 700, which consists of 6 families, 25 genera, 30 species8. The characteristics of ecological distribution and diversities of butterflies community were studied, and the abundance, dominance and diversity indexes for the five habitat types and different altitudes were calculated and analysed. The results show that the characteristics of ecologiced distribution of butterflies are primarily affected by dry climate, and the species richness decreased in the follow sequence: desert grass-rand, mountain forest, oases desert, alpine meadow. In general, the diversity indexes of butterfly decreases with rising of altitudes. |
