摘要
影响黄鼠数量变动的外因有气象因子、生物因子、土壤因子和人的活动。气象因子包括温度、湿度、光照、风速等；生物因子包括植物、动物、微生物等；土壤因子包括化学成分、物理结构等；人的活动包括灭鼠以及破坏生态平衡等。保护环境，破坏鼠的生存条件是最根本、最有效的控制鼠患的方法。
The paper describes external factors which influence the population change of Citellus dauricus brandt . Climatic factors include temperature, humidity, light radiation, wind speed; Biological factors include plants, animals and micro-organism; Soil factors include chemical composition and physical structure; Human activities include rodent control and damaged environment. The basic and effective way to control rodent is protecting environment and destroy livng conditions of rodents.
