一、研究方法1.甘肃鼢鼠密度调查。甘肃鼢鼠营地下穴居生活,其洞道结构复杂、弯曲串通,地上土堆密布,很难直接查明其种群数量和活动,一般以相对指标来推算其数量。有三种统计方法:土丘系数统计法:在有代表性的林地设置若干样地1公顷,统计其中鼢鼠拱出的土丘数,然后挖开鼠洞用鼠夹捕杀、捕捉样地内所有鼢鼠,直至无封洞现象为止,计算土丘群系数。
First, research methods 1. Gansu zokor density survey. Gansu zokor camp under burrowing life, the cave structure is complex, curly collusion, mound on the ground overcast, it is difficult to directly identify the number and activity of its population, the relative index to estimate its general quantity. There are three statistical methods: mound coefficient statistics: in a representative of the woodland set a sample of 1 hectare, which counts the number of mound arches out, and then dig the mouse hole murder with a mouse trap to capture all 样Rats until the phenomenon of no holes, calculate the mound group coefficient.
