在秦岭漳平洞中发现了3种微齿动物，分别为Microtus oEconus、Caryomys Inez和Caryomys Eva。它们是气候敏感型物种，具有不同的生态习性，因此它们的分布很好地对应于环境变化。通过与现今化石微体分布的统计对比表明，研究区及其邻近地区自中更新世以来的气候变化为：493ka前温暖潮湿，259ka前凉爽潮湿，205ka前寒冷湿润，28ka前凉爽湿润，现在暖干。
Three microtine species are recovered from the Zhangping Caves of the Qingling Mountains, namely Microtus oeconomus, Caryomys inez and Caryomys eva. They are climate-sensitive ones with different ecological habits, therefore their distribution well corresponds to environmental variations. Statistical comparison of the distribution of fossil microtines and their counterparts nowadays displays that the climate variation of the studied area and its contiguity since the middle Pleistocene are: warm and humid at 493 ka ago, cool and humid at 259 ka ago-cold and humid at 205 ka ago-cool and humid at 28 ka ago, and warm and dry at present.
