青藏高原野牦牛分布点位数据（1872-2022年）

野牦牛分布点数据收集的年限为1872—2022年，通过ArcGIS对一些文献中涉及到的野牦牛分布进行点位地理位置匹配校正与矢量化，进而获得野牦牛的分布数据，并删除重复记录和经纬度信息不完整的数据，最终参与模型构建的现代野牦牛分布点有效数据291个，其中285个来自国内外已公开发表的文献资料，4个来自全球生物多样性数据库(GBIF，https://www.gbif.org)，2个来自实地调查。The collection period of wild yak occurrence records spans from 1872 to 2022. Wild yak distribution locations mentioned in relevant literature were spatially matched, calibrated and vectorized using ArcGIS to obtain the wild yak distribution dataset. Duplicate records and data with incomplete longitude and latitude information were subsequently removed. Finally, 291 valid modern wild yak occurrence records were retained for model construction, including 285 sourced from peer-reviewed literature published both domestically and internationally, 4 from the Global Biodiversity Information Facility (GBIF, https://www.gbif.org), and 2 from field surveys.
