摘　　要：通过在红庄林场不同土地利用类型随机设立13处样方,调查甘肃鼢鼠密度、样方内植被的种类及每种植被所占比例,结果表明:样方内甘肃鼢鼠密度与菊科植物比例成显著正相关,与禾本科植物比例成显著负相关,回归方程分别为:y=1.518 3x1-5.330 8和y=71.678 0-1.891 1x2。甘肃鼢鼠喜食的植物依次为菊科、禾本科、杂类草。Thirteen sample plots were set in the Hongzhuang forest farm randomly according to different uses of land, to investigate Zoker population, vegetation types and composite coverage. The result showed that zoker population is in positive correlation with the proportion of vegetation coverage while in negative correlation with the coverage of gramineae. Regression equation is： y= 1. 518 3xl- 5. 330 8 and y= 71. 678 0-- 1. 891 1x2. The favorite plant for zoker in order is Composite, Gramineae and subordinate grass.
