青藏高原大型野生食草动物维持量（2020）

本研究的数据内容主要围绕青藏高原大型野生食草动物的分布和密度展开，空间分辨率为1km。数据来源于全球生物多样性信息平台、国家青藏高原科学数据中心以及第二次青藏科考调查数据，并通过文献报告中的图像点位数据补充。剔除空间自相关点后（以0.5km为缓冲半径），基于先验密度约束的模型模拟了五种动物的空间密度，并使用转换系数将野牦牛、藏野驴、藏羚羊、藏原羚和白唇鹿头数换算为标准羊单位。数据应用成果体现在这些数据反映了各物种在青藏高原的空间分布特征及其生态承载力，为生态保护和资源管理提供了重要依据。

This study's data focuses on the distribution and density of large wild herbivores on the Qinghai-Tibet Plateau, with a spatial resolution of 1 km. The data were collected from the Global Biodiversity Information Platform, the National Scientific Data Center for the Qinghai-Tibet Plateau, and survey data generated by the Second Qinghai-Tibet Plateau Scientific Expedition, and were further supplemented by image point data from published literature reports. After removing spatially autocorrelated points with a buffer radius of 0.5 km, spatial densities of five target species including wild yak, kiang, Tibetan antelope, Tibetan gazelle, and white-lipped deer were simulated using a model constrained by prior density information. Conversion coefficients were then applied to convert the population counts of these five species into standard sheep units (SSU). The application value of this dataset lies in that it reflects the spatial distribution characteristics and ecological carrying capacity of each species across the Qinghai-Tibet Plateau, providing an important basis for ecological conservation and natural resource management.
