| 摘 要： | 1998年5～6月。在新疆新源县纳孜确鹿特山地草甸类草地自然保护区对伊犁田鼠的生态学进行了调查研究。以伊犁田鼠铗捕率为因变量．以高度、盖度、植物种数等8种生境因子为自变量进行逐步回归分析．结果表明．伊犁田鼠夏季生境选择主导因素为：草群高度、盖度、产草量(正相关)。鼠种数(负相关)，复相关系数R=0．9959，F=389．92，为极显著相关。

| Abstract: | A research of habitat selection of tian shan vole (Microtus iliaeus) was conducted on Naziquelute mountain meadow Grassland Reserve in Xinyuan county in May-June, 1998. Results obtained were as follows: Trap night method was used to determine the density of tian shan vole on 18 plots of different environment.The eight ecological factors including height, coverage, plant species, etc were analyzed. The gradual regression analysis of the capture rate of tian shan vole (y) and ecological factor (x_i) declared that density of tian shan vole was correlated with height, coverage and yield of grassland , negative correlation with number of rodent species in community ,multi-correlation ratio=0.9959, F=389.92, RF-test was very significant. |
