八面山两栖动物多样性研究初报

Preliminary studies on diversity of amphibian in Bamian Mountain of Hunan province

20 0 1年 6～ 8月对湖南省八面山两栖动物多样性进行了初步研究 .结果表明 :八面山两栖类群落物种丰富 ,共计 7科、12属、2 1种 ;群落的多样性因生境、海拨不同而异 ,以流溪最高、静水最低 ,并且与海拨高度呈显著负相关 ;不同海拨的两栖类群落可依相似性系数分成两个垂直带 .

From June to August in the year 2001, this paper researched the diversity of amphibians in Bamian Mountain, which is the seventh highest mountain in Hunan Province and the first highest in Huaihua City. the results shows: the species of amphibian communities in Bamian Mountain are very abundant, and there are a total of 7 families? 12 genunes and 21 species; the diversities of the communities are changable due to the different habitat and elevation, and the rivulet model have the largest number of diversities while the static water model have the least, and also the diversities are significant negative correlation with the height of the elevation, the communities of amphibian in different elevations can be divided into two perpendicular regions according to the similar cofficient.
