摘要: 根据内蒙古自治区伊克昭盟鄂托克旗和鄂托克前旗1975-1989年长爪沙鼠密度监测数据和本地区气象站的7项气象因子资料,给出了气象因子与鼠密度的最优回归子集模型和标准回归模型。得到结论:年降水是影响鼠数量变动的最重要的气象因子。求出了年降水与鼠密度的曲线回归模型。

Abstract: According to the population of Meriones unguiculatus and 7 factors data of meteorological phenomena in Etuoke qi and Etuoke qianqi of Yikzhao Meng.Inner Mongolia Autonomous region in 1975- 1989.the optimum regression subsets of multipic linear regression analysis is conducted.The model of standard regression is also obtained. The conclusion is as following:Yearly rainfall is a main factors of meteorological phenomena affecting Meriones unguiculatus populations.The model of curve regression analysis between the yearly rainfall and the population of Meriones unguiculatus is given.
