青海野牦牛、藏羚、棕熊分布及栖息地调查数据集（2021）

子课题（2019QZKK05010411）以野牦牛、藏羚和棕熊种群调查监测为核心内容，开展系统而持续的野外考察工作，查清它们的地理分布、种群数量、种群结构等，开展适宜栖息地评估。分别选取其分布区和潜在分布区，划分为多个子区域，根据生境类型、气候、海拔等因素采用分层随机抽样，分别采用总体计数法、可变距离样线法或固定宽度样线法进行考察。同时针对棕熊的极低遇见率，结合访谈法进行。考察区域主要包括青海省玉树藏族自治州、海西蒙古族藏族自治州、海北藏族自治州和其他州县该三种动物的分布区和潜在分布区，以期掌握青海省境内的野牦牛、藏羚、棕熊分布和五年的种群动态情况。本数据集包含2021年在青海调查牦牛、藏羚和棕熊拍摄的照片和视频。

Subproject (2019QZKK05010411) conducted systematic and continuous field investigations centered on the population survey and monitoring of wild yaks, Tibetan antelopes and brown bears, aiming to clarify their geographic distribution, population size, population structure and other basic ecological status, and carry out suitable habitat assessment. We selected their respective distribution and potential distribution areas, divided them into multiple sub-regions, adopted stratified random sampling based on factors including habitat type, climate and altitude, and implemented surveys using the total count method, variable distance transect method or fixed width transect method respectively. Given the extremely low encounter rate of brown bears, interview surveys were also integrated into the investigation work. The survey areas mainly cover the distribution and potential distribution areas of the three target species in Yushu Tibetan Autonomous Prefecture, Haixi Mongolian and Tibetan Autonomous Prefecture, Haibei Tibetan Autonomous Prefecture and other prefectures and counties of Qinghai Province, with the ultimate goal of mastering the distribution and five-year population dynamics of wild yaks, Tibetan antelopes and brown bears within the territory of Qinghai Province. This dataset includes photos and videos captured during the 2021 field survey targeting wild yaks, Tibetan antelopes and brown bears in Qinghai Province.
