摘要
啮齿动物的种群调节理论一直是业内研究者争论的重点,在自然界中,种群数量变动的影响因素以及它们的相互作用极为复杂,越来越多的研究认为外在因素对种群变化起到关键作用。在查阅大量文献的基础上,对小型啮齿动物种群数量造成波动的外在因素进行了综述,概述了食物、降雨、降雪以及温度对不同种类啮齿动物种群的影响。
The population regulation theory of rodent is always the controversial focus to the researchers. The influencial factors of population change and their interactions were very complex. More and more researches consider that the environmental factors play a key role in rodent population change. The envi- ronmental factors that affect population fluctuation of rodent, such as food, rain, snow, and the tempera- ture were summarized based on reviewing extensive literatures.
