摘　　要：2014~2016年在阿拉善荒漠区选择开垦、轮牧和禁牧三种典型生境,应用夹日法对五趾跳鼠和三趾跳鼠进行野外调查,并对两种跳鼠的年龄结构及其季节变化特征进行分析。结果表明,在三种不同类型生境中五趾跳鼠和三趾跳鼠均以II龄组数量为最高;五趾跳鼠种群在开垦生境中为下降型种群,在轮牧和禁牧生境中夏季为增长型种群,春季和秋季为下降型种群;三趾跳鼠种群在开垦和轮牧生境中3个季节均为下降型种群,在禁牧生境中春季为增长型种群,夏季为下降型种群。From 2014 to 2016,Allactaga sibirica and Dipus sagitta were investigated by trap-day method in three typical habitats of reclaimed,rotation grazing and prohibit grazing in Alxa desert area,and the age structure and seasonal variation characteristics of the two species of jerboa were analyzed.The results showed that in three different habitats,the number of II-age group was the highest of both Allactoga sibirica and Dipus sagitta,the population of Allactaga sibirica in the reclaimed habitat was a declining population,while in the rotation grazing and prohibit grazing habitat,it was increasing populations in summer,and declining populations in spring and autumn.The population of Dipus sagitta in the reclaimed and rotation grazing habitats was a declining population in 3 seasons,while in prohibit grazing habitat it was a decreasing population in spring and a declining population in summer.
