摘要
本文报道贵州省两栖动物63种,其中省新纪录2种,即阔褶蛙和锯腿树蛙。将贵州划分为黔西高原中山、黔北中山峡谷、黔中山原丘陵、黔东南低山丘陵盆地和黔南低山河谷五个动物地理省。认为黔南低山河谷省属于向华南区过渡的华中地带。讨论了各动物地理省的地貌、气候、两栖动物区系特征及地理替代种类。分析了各动物地理省两栖动物区系的相似性及数量关系。
63 species and subspecies of amphibians belonging to 19 genera, 9 families and 2 orders have been collected in Guizhou province. There are 2 new provincial records, Rana latouchii and Rhacophorus cavirostns. A zoogeographical analysis of the amphibians fauna shows that it consists of five kinds of elements. Central Chinese elements, Central and Southern Chinese elements, Southwest-plateau elements , Southern Chinese elements and Palaearctic and Oriental elements.
It is suggested that with respect to its amphibians fauna, Guizhou may be further divided into five faunal provinces.
In the western faunal province the Southwest-plateau elements are dominant. It belongs to Southwestern China region.
In the northern and southeastern faunal provinces the Central Chinese elements are dominant. They belong to Central China region.
In the central faunal province the Central and Southern Chinese elements arc dominant. It belongs to Central China region.
In the southern faunal province the Central and Southern Chinese elements are dominant. The region belonging to Central China region is considered to be a transitional zone between the Central Chinese and the Southern Chinese region.
The similar degree of the amphibians among five faunal province has been calculated.
