摘 要 ：１９９２年４月￣１９９５年４月作者在河南灵宝程村黄土塬农作区对棕色田鼠种群数量进行了逐月调查。结果表明，春季３、４月份种群数量高，夏季７、８月份数量低，而秋季１０月份数量又高，然后又降低，呈典型的双峰型。在对棕色田鼠种群年龄结构、繁殖强度等研究的基础上，探讨了种群消长机理和种群调节因子。发现３个月前的成亚比、２个月前的繁殖强度、温度指数、降雨量指数分别和密度呈显著相关，用以上因子建立多元回归方程预

Abstract:The populations dynamics of mandarin vole were investigated every month from April 1992 to April 1995 in agriculture area on loess plateau in the west of Henan. According to statistical data, the seasonal fluctuation of mandarin vole exhibited a high-low-
