| 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. |
