数据摘要

Collect and sort out the ground sampling data of the extant biomass on the grassland in Eurasia. Based on the satellite remote sensing surface reflectance data products, build the inversion model of the vegetation index and the extant biomass on the grassland of different grassland types, and calculate the data products of the extant biomass on the main pastures in Eurasia in different years. This index can be used to reflect the utilization of the grassland.
