西双版纳自然保护区鼷鹿生境选择的初步研究

Preliminary Study on Habitat Selection of Tragulus javanicus williamsoni Kloss in Xishuangbanna Nature Reserve

对中国仅见于西双版纳勐腊县鼷鹿（ＴｒａｇｕｌｕｓｊａｖａｎｉｃｕｓｗｉｌｉａｍｓｏｎｉＫｌｏｓ）栖息地生境因子的调查分析，初步得出鼷鹿栖息环境与植被类型、下木、地被、坡度、坡向、海拔、土质的相关程度。对各生境因子的优先选择顺序分别为：下木郁闭度，地表覆盖物，坡度，植被类型，土质，海拔，坡向。并初步划分出鼷鹿的４个生境等级为：（１）最佳生境地；（２）良好生境地；（３）一般生境地；（４）劣等生境地。并在此基础上提出相应的保护对策。

Based on the investigation and analysis on the habitat of Tragulus javanicus williamsoni Kloss in Mengla county of Xishuangbanna prefecture,the correlation degrees between the vegetation type,underwood,groundcover,gradient,exposure,altitude,soil texture and habitat were worked out. The importance of the habitat factors of Tragulus javanicus declined in the order of crown density of underwood,amount of ground cover,gradient,vegetation type,soil texture,altitude and exposure.The habitat of X]Tragulus javanicus was graded as 4 kinds of optimum habitat,good habitat,ordinary habitat and faulty habitat.Besides,the corresponding countermeasures to protection of the habitat of Tragulus javanicus were worked out.
