本文根据内蒙古荒漠草原区1971～1993年的天文、气象和长爪沙鼠种群数量资料，应用多元回归和逐步回归分析方法，建立了长爪沙鼠数量预测预报的数学模型。为预测预报提供了依据。
Based on the data of astronomy, meteorology and Mongolian gerbil (Meriones unguiculatus) population from 1971 to 1993 in the desert steppe region of Inner Mongolia, the mathematic model of Mongolian gerbil (Meriones unguiculatus) was established based on multiple regression and stepwise regression analysis. Provided the basis for forecasting and forecasting.
