摘要
本文报道了宁夏特有的脊椎动物六盘齿突蟾仅分布于六盘山自然保护区的二龙河、梁殿峡沟和香水河上段海拔1900m～2500m，总长度114km的溪流中，均属泾源县境。用等距抽样调查方法调查，并用调查强度系数修正所估计的种群数量为19680～36547只，平均每千米溪流173～321只，总分布面积不足1km2。文章还报道了形态、生态方面的有关资料，并对调查方法、雌雄性比等问题进行了讨论。
In this paper it is reported that the special vertebrate species in Ningxia,Scutiger liupansis, which is only distributed in the Erlong Stream, the Liangdianxia Stream and the begining of the Xiangshuie Stream of the Liupanshan National Nature Reserve, and the altitudes of its distribution range are 1900-- 2500 meters. Those streams are all situated in Jingyuan County, Ningxia and the total length of the streams where Scutiger liupanensis is distributed is about 114 kilometers. By equal distance spot--check investigation method and amended the data with investigation intensity coeficient, the population quantity are calculated to be 12, 596 - 25, 054, average quantity of one kilomater stream are 114- 211. The area in which Scutiger liupanensis lives is less than a square kilometer. This paper also reports some data about morphology and ecology on this species and discusses on investigation methods and sex ratio.
