欧亚大陆主要放牧草原地上现存生物量数据集（2000-2020）

收集整理欧亚大陆草原地上现存生物量地面采样数据，基于卫星遥感地表反射率数据产品，构建植被指数与不同草原类型草原地上现存生物量的反演模型，计算获得不同年份欧亚大陆主要放牧草原地上现存生物量数据产品，该指标可用于反映草原的利用状况。

This study collected and organized ground sampling data of above-ground standing biomass in Eurasian steppes. Based on satellite remote sensing surface reflectance data products, inversion models were developed between vegetation indices and above-ground standing biomass of different steppe types. Subsequently, above-ground standing biomass data products of major grazing steppes across Eurasia across multiple years were calculated and generated. This indicator can be used to reflect the utilization status of grasslands.
