Abstract: An investigation on the population density of brandt's vole in the typical steppe in Zheng xiang bai County, Inner Mongolia was carried out from May to September during 1987-1990. After further analysis, three regression equations for prediction were presented according to subadult- adult ratio of females, percentage of pregnant females and sex ratio. The results are as follows:1. Y7=37.500-68.002X5(r=-0.998>r(0.05), n=3).2. Y8=102.792-1.277X5(r=-0.998>r(0.05), n=3).3. InY9= 16.861-13.714X7(r=-0.999>r(0.05). N=3).where Y7, Y8 and X7 represent respectively capture rate of July, capture rate of September and sex ratio(♀/♂)of July, X5 in the first and second eqnations represent respectively subadult-adult ratio of femalges and percentages of pregnant females. But the three equations are Just suitable for brandt's vole population which is decreasing after it has broken out.
摘要: 本文对布氏田鼠种群数量的年际动态和季节动态作了初步分析,并根据雌鼠怀孕率、雌鼠亚成比和性比三项种群特征,提出预测布氏田鼠种群动态的三个短期(2~4个月)方程式。
