放牧轨迹及放牧强度数据集（2019）

采用动物佩戴式定位器，结合DJ无人机航拍，在色尼区罗玛镇、安多县措玛乡、安多县强玛镇、班戈县普保镇等典型牧场开展家畜放牧轨迹监测，采用一定时间栅格内放牧点数与牧场总点数的比例表征放牧选择概率，模拟了牧场尺度的牲畜放牧强度。数据监测时间为2019年6月1日-8月31日。数据集空间分辨率为50m，主要信息包括栅格尺度畜群出现点数（Join_Count）及放牧选择概率（ratio）。数据投影为WGS 1984 UTM Zone 45N。该数据集可用于草地利用与畜群放牧管理研究。

Livestock grazing trajectory monitoring was conducted in typical pastures including Luoma Town of Sênnyi District, Cuoma Township of Amdo County, Qiangma Township of Amdo County and Puba Town of Bangoin County, using animal-borne positioning loggers combined with DJ drone aerial surveys. Grazing selection probability was characterized by the ratio of the number of grazing points within a specified temporal grid to the total number of points in the pasture, to simulate livestock grazing intensity at the pasture scale. The data monitoring period was from June 1 to August 31, 2019. The dataset has a spatial resolution of 50 m, and its main information includes the number of herd occurrence points at the grid scale (Join_Count) and grazing selection probability (ratio). The data projection is WGS 1984 UTM Zone 45N. This dataset can be used for research on grassland utilization and livestock grazing management.
