海南岛马鞍岭火山口地区翼手目物种多样性

Species Diversity of Chiroptera in Ma′anling Volcano Area,Hainan Island

马鞍岭火山口为海南岛的重要农业区和旅游地,为了解该地区的动物资源,2004年我们对该地区的翼手目种类进行了调查。结果显示,马鞍岭火山口地区共有翼手目动物10种,隶属4科7属,占海南岛已知翼手目种类(31种)的32.3%,具有较高的翼手目物种多样性,其香农-维纳指数为2.734、均匀性指数为0.823、辛普森指数为0.817。本文还分析了马鞍岭火山口地区翼手目的区系特点,并对其物种的多样性和分布特征进行了讨论。

Abstract：Ma＇anling volcano area is an important region for agriculture and tourism in Hainan Island. In order to understand its species diversity of Chiroptera, the species and population abundance of Chiroptera were investigated in 2004. A total of 10 species of Chiroptera, belonging to 4 families and 6 genera, were recorded in the area, which takes 32.3% of the 31 Chiroptera species in whole Hainan Island. The Shannon-Weiner index is 2.734, Index of evenness is 0.823, and Simpson index is 0.817. The fauna characteristics was analyzed. The diversity and some biological characteristics, such as rooster and winter hibernation of Chiroptera species in this subtropical and tropical island, were also discussed.
