According to the live coefficient c , we modified the predictions for this age group and come to a conclusion that is corresponding to actual field data . in other words , the numbers of - age and - age were nearly zero with their densities below 4 / hm2 . these results suggest that l . lagurus population began to decline 運(yùn)用校正后的存活系數(shù)繼續(xù)預(yù)測(cè),其結(jié)果與2001年9月的野外調(diào)查結(jié)果基本一致,證實(shí)當(dāng)年草原兔尾鼠的數(shù)量非常少,低于4 . 0只/公頃,且齡鼠和齡鼠幾乎為零。
