| 摘 要： | 通过对秦岭山区中国大鲵(Andrias davidianus)栖息地生境因子调查、统计,利用R语言分析了各因子与大鲵生境选择的相关性,得出研究结果:秦岭山区影响大鲵生存的主要因子为栖息地类型(相关系数r=0.98),其次是水温(相关系数r=-0.8)、河岸坡度(r=-0.6)和p H (r=-0.6);浊度(相关系数r=0.5)、电导率(r=0.49)、DO(r=0.4)、人为干扰(r=0.35)和海拔(r=0.31)对大鲵分布影响不大。研究结果为探讨中国大鲵对野生环境的适应性选择提供了参考。

| Abstract: | By investing and counting of the habitat factors of Chinese giant salamanders(Andrias davidianus)in Qinling Mountains,this study analyzed the correlation between factors and habitat selection of Chinese giant salamanders(Andrias davidianus)by R language.The results showed that the main factor,which affected the presence of giant salamanders was the habitat type(correlation coefficient r=0.98),followed were water temperature(correlation coefficient r=-0.8),river bank slope(r=-0.6),and pH(r=-0.6).By contrast,turbidity(correlation coefficient r=0.5),conductivity(r=0.49),DO(r=0.4),human disturbance(r=0.35)and elevation(r=0.31)had little impact on the distribution of Chinese giant salamanders(Andrias davidianus).This study might provide a reference for studying the adapt selection for the wild habitat of Chinese giant salamanders(Andrias davidianus). |
