1980年以来青藏高原草地生产力数据

数据集包含1980，1990，2000，2010，2017年青藏高原草地产草量空间分布。基于中国科学院地理科学与资源研究所具有自主知识产权的生态水文动力模型VIP（Vegetation Interface Process) 模拟了青藏高原草地总初级生产力（GPP），利用经验系数估算了净初级生产力（NPP），将NPP换算为干物质，再根据根冠比估算了干草产量。空间分辨率1公里。该数据集将为草地资源管理、开发、利用以及“以草定畜”策略的制定提供依据。

This dataset provides spatial distribution data of grassland forage yield across the Qinghai-Tibet Plateau for the years 1980, 1990, 2000, 2010 and 2017. The Gross Primary Productivity (GPP) of grasslands on the Qinghai-Tibet Plateau was simulated using the eco-hydrological dynamic model VIP (Vegetation Interface Process) with independent intellectual property rights developed by the Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences. Net Primary Productivity (NPP) was estimated using empirical coefficients, converted into dry matter, and the hay yield was subsequently calculated based on the root-shoot ratio. The dataset has a spatial resolution of 1 kilometer. This dataset can serve as a scientific basis for the management, development and utilization of grassland resources, as well as the formulation of the "forage-based livestock stocking" strategy.
