青藏高原典型县域载畜量空间数据及图集（2019-2022）

2019至2022年，草蓄平衡科考分队在一江两河、可可西里、羌塘高原、藏东南、三江源、祁连山南坡与柴达木盆地等关键科考区收集整理县域尺度青藏高原家畜数据。通过青藏高原县域统计调查得到了各县区载畜量，在此基础上使用人口数据进行加权空间化得到了载畜量空间格局（单位：标准羊单位每公顷，SU ha-1）。该数据集的完成可为制定区域水平的草畜平衡区划方案、优化畜牧业发展布局、构建科学的草地分类治理与管理提供必要的数据支持。From 2019 to 2022, the Grass-Livestock Balance Investigation Team collected and sorted out livestock data of the Qinghai-Tibet Plateau at the county-level scale in key investigation areas including the Yarlung Zangbo River and its two tributaries, Hoh Xil, the Qiangtang Plateau, Southeastern Tibet, the Three-River Source Region, the southern slope of the Qilian Mountains, and the Qaidam Basin. The livestock carrying capacity of each county was obtained through county-level statistical surveys of the Qinghai-Tibet Plateau. Based on this, the spatial pattern of livestock carrying capacity (unit: standard sheep unit per hectare, SU ha⁻¹) was derived via weighted spatialization using population data. Completion of this dataset can provide essential data support for formulating regional grass-livestock balance zoning plans, optimizing the development layout of animal husbandry, and establishing scientific grassland classification-based governance and management systems.

背景概述

该数据集提供了2019至2022年青藏高原典型县域的载畜量空间数据，基于科考调查和统计资料，通过人口加权空间化方法生成，以标准羊单位每公顷（SU ha-1）为单位，空间分辨率为10m至100m，格式为TIF。其特点是覆盖一江两河、可可西里、羌塘高原等多个关键区域，旨在为草畜平衡区划、畜牧业布局优化和草地管理提供数据支持，数据来源于第二次青藏高原综合科学考察研究项目。
