摘要
根据内蒙古自治区伊克昭盟鄂托克旗查布苏木和鄂托克前旗布拉格苏木在1981～1990年4～5、10～11月份调查的长爪沙鼠密度资料,建立了种群增长指数模型N_t=0.22936exp {1.18135t} (P<0.05)。种群增长超指数模型N_t=0.43912exp {0.19232t^(2.4)} (P<0.005),种群负增长指数模型N_t=1318.44725exp{-0.60723t} (P<0.005)。
According to the population data of Meriones unguiculatus from April to May and October to November in 1981～1990 in Etokeqi and Etokeqianqi, Inner Mongolia Autonomous Region, wehave set up the exponentieal model of the population growth N_1=0.22936exp {1.18135t} (P<0.05), the hyperexponentical model of the population growth N_1=0.43912exp {0.19232t^(2.4)} (P<0. 005) and the exponentical model of the population negative growth N_1 = 1318. 44725exp {-0. 60723t} (P<0.005).
