Plateau pikas () are regarded as one of the main causes of the degradation of alpine meadows in the Qinghai-Tibet Plateau (QTP). The population density of plateau pikas is directly related to the degree of grassland damage. In this study, field observation was conducted for one week in the southeastern QTP in August 2019. A random encounter model (REM) was used to estimate the population density of plateau pikas from photographs and videos, and the frequencies of different behaviors were calculated. In addition, the effects of water-source distance and terrain on the distribution of plateau pikas and the frequencies of different pika behaviors under different population densities were explored. The observations and knowledge derived from this study provide a reference for the population control of plateau pikas.
高原鼠兔被认为是青藏高原高寒草甸退化的主要原因之一。高原鼠兔的种群密度与草地破坏程度直接相关。本研究于2019年8月在青藏高原东南部进行了为期一周的实地观察。采用随机相遇模型（REM）从照片和视频中估计高原鼠兔的种群密度，并计算不同行为的频率。此外，还探讨了水源距离和地形对高原鼠兔分布的影响以及不同种群密度下高原鼠兔不同行为的频率。本研究得出的观察结果和知识为高原鼠兔的种群控制提供了参考。
