摘　　要：2007年7月～2008年7月,对海南岛翼手类动物进行了物种多样性调查。按照《世界哺乳动物名典》和Simmons的分类系统进行分类,结合考察标本记录,整理调查结果和文献资料。统计海南岛翼手类动物计37种,隶属于2亚目7科(包括采集标本,计16种,隶属于2亚目4科)。依据分布型对其组成成分进行分析,结果表明海南岛翼手类动物东洋界种类相对较多,反映出强烈的华南区的特征;岛屿的影响表现在亚种分化和缺乏某些大陆类群。依物种组成对分布区进行聚类分析,结果呈现明显的四阶现象。根据物种多样性组成和聚类分析结果,可以认为以乐东、东方和陵水为主要区域范围的尖峰岭和吊罗山两大山系是目前统计海南岛翼手类物种分布的热点区。From July 2007 to July 2008,an investigation on species diversity of Chiroptera was carried out in Hainan island.According to the classification system of the ＂mammals species of the world＂ and Simmons,the field investigation findings and the records in foretime were collected.37 species of bats in Hainan island,belonging to 7 families,2 suborders,were recorded （16 species of bats in Hainan island,belonging to 4 families,2 suborders,were found in our investigation）.The analysis on the distribution pattern based on its species composition was conducted.Results showed that the oriental types of Chiroptera animals in Hainan island are relatively high,reflecting that the typical characteristics of the south China area and the lack of some mainland groups existed,and islands affect performance in the sub-species differentiation.Depending on the cluster analysis on the distribution area based on its species composition,the results showed clear signs of fourth-order phenomenon existed.The whole results of the composition of species diversity and cluster analysis showed that the Diaoluo mountain and Jianfeng mountain,which are situated in the major ranges of Ledong,Dongfang and Lingshui respectively,can be considered as the distribution hotspot of Chiroptera in Hainan island.
