摘要
Understanding the population size of animals is crucial for formulating scientific management policies, especially for endangered species. The central area of the Qinling Mountains in Shaanxi is a vital area for forest musk deer, but research is insufficient and estimates of its population size are lacking. In this study, we constructed a species distribution model for the forest musk deer in the central Qinling Mountains in Shaanxi using topography, land-use, and bioclimatic variables alongside forest musk deer occurrence data. The Time-to-Event (TTE) model was employed to estimate the population density of forest musk deer in the selected survey area. By utilizing the suitable habitat area provided by the species distribution model, the population density in the central Qinling Mountains of Shaanxi was estimated by extrapolating from the survey area. Our estimate of the population size of forest musk deer in the central Qinling Mountains of Shaanxi is approximately 2722 ± 788. Similar population estimation methods could be more widely applied, especially in areas with limited survey resources.

了解动物的人口规模对于制定科学管理政策至关重要，尤其是对于濒危物种。Shaanxi的Qinling山的中心区域是森林麝香鹿的重要区域，但研究不足，缺乏对其人口规模的估计。在这项研究中，我们使用地形，土地利用和生物气候变量与森林麝香鹿出现数据一起建造了Shaanxi中央Qinling山脉森林麝香鹿的物种分布模型。采用了事件时间（TTE）模型来估计选定的调查区域森林麝香鹿的种群密度。通过利用物种分布模型提供的合适的栖息地区域，通过从调查区域外推估计了Shaanxi中央Qinling山的种群密度。我们对Shaanxi中部QINLING山区森林麝香鹿的人口规模的估计约为2722±788。可以更广泛地应用类似的人口估计方法，尤其是在调查资源有限的地区。
