【摘要】 高原鼠兔作为青藏高原特有小型哺乳动物,环境因素对其分布有着重要影响,对其进行相关性研究,能够为高山草地生态系统的可持续提供基础科学依据。文章采用随机样线方法,对拉萨市墨竹工卡日多乡、山南市浪卡子县和日喀则市江孜县热龙乡内的高原鼠兔有效洞穴数分布进行了调查,并采集相关环境参数数据和高原鼠兔有效鼠兔洞口数。结果显示:高原鼠兔有效洞穴数的分布与水源距离间没有相关性(rho=0.07,S=17766100,P=0.298);高原鼠兔有效洞穴数的分布与海拔高度之间呈负相关(rho=-0.25,S=2366000,P=0.00019);高原鼠兔有效洞穴数与N-E、SW-NE呈相关;与NE-E、SW-E、NE-N、SW-N呈正相关。更多还原

【Abstract】 Plateau pika is an unique small mammal on the Qinghai-Tibet Plateau,the study on correlation between environmental factors and distribution of plateau pika can provide a scientific baseline for the sustainable development of alpine grassland ecosystem.The numbers of burrow of plateau pika and relevant environment factors were measured through the line transects in different study areas including Rudog in Muozhu Gongga,Langkazi in Lhuega and Gangzi in Shigazi.The results showed that there was no correlation between the distribution of plateau pika and the distance to water(rho=0.07,S=17766100,P=0.298).However,with increasing the elevation,the numbers of burrow were decreased(rho=-0.25,s=2366000,P=0.00019).In terms of aspects,there were negative correlation between the numbers of burrow and N-E,SW-NE,yet here were positive correlation between the numbers of burrow and NE-E,SW-E,NE-N,and SW-N.更多还原
