摘　　要：依文献记载,在西双版纳州设定鼷鹿调查范围,运用访问调查法对74个村民小组进行调查,共有120位受访者提供有效信息。运用Arc GIS 10.5软件对调查数据进行处理,得出鼷鹿水平分布范围为勐腊县北纬22.189 752°~21.149 920°,东经100.614 550°~101.776 686°,分别位于勐腊、瑶区、勐伴、易武、勐满、磨憨(尚勇)、关累、勐捧8个乡镇。通过红外相机调查,发现鼷鹿栖息的海拨范围为624~1 099 m,以海拨600~900 m为主,占总栖息范围的83.35%。鼷鹿种群受到的主要威胁有生境破碎化、猎杀、林下经济发展等。提出加强鼷鹿栖息地保护、严肃查处猎杀鼷鹿的行为、做好生境恢复工作等保护策略。At present, the wild Asian elephant in China only occurs in three areas of Yunnan, with a total population of 288 - 338 individuals. The wild Asian elephants in Xishuangbanna amounts to 228 - 279 individuals and five independent populations. Since 2005, there has been the remarkable change in the amount and distribution of the wild Asian elephants. This paper conducted a systematic study on the dis- tribution and transition of the wild Asian elephants in Xishuangbanna with synchronous investigation, tracking, and interviewing methods. The results showed that the wild Asian elephants trended increasing in population and dispersing in distribution from the protected areas outward neighboring state forests or community forests. This paper put forward suggestions to build ecological corridors connecting the isolated elephant populations in order to solve sever problems including highly - fragmentation of habitat and dis- turbance from agricultural development.
