摘要: 根据鄂尔多斯荒漠草原1981~1986年年降水和四季降水,长爪沙鼠年均密度和4~5月、10~11月密度资料,经多元回归分析认识到,鼠疫动物病流行前的年降水,特别是6~8月降水是影响长爪沙鼠种群数量变动的主要因素;给出7种不同条件下预报鼠密度的数学模型。

Abstract: We studied the meterials by multiple regression analysis, the data are yearly rainfall, season rainfall, yearly density of Meriones unguiculatus, month density of April to May, October to November in the period of 1981~1986 in Erdosi desert-grasslands, the conclusions are as following: before the plague outbreak, (1) Yearly rainfall especially in June to August is amain factor affecting Meriones unguiculatus population. (2) A mathematical model suggested the prediction at density under seven different conditions.
