Based on a large number of measured aboveground biomass data of grassland, the temperate grassland types were divided according to the vegetation type map of China in 1980s Based on the Landsat remote sensing data of engine platform, the random forest model of grassland aboveground biomass and remote sensing data was constructed for different grassland types. On the basis of reliable verification, the annual aboveground biomass of grassland from 1993 to 2019 was estimated, and the annual spatial data set of aboveground biomass of temperate grassland in Northern China from 1993 to 2019 was formed. Aboveground biomass is defined as the total amount of organic matter of vegetation living above the ground in unit area. The original grid value has been multiplied by a factor of 100, unit: 0.01 g / m2 (g / m2). This data set can provide a scientific basis for the dynamic monitoring and evaluation of temperate grassland resources and ecological environment in northern China.

File naming and required software

File name: Grassland aboveground biomass data set is stored in grid TIF format, and the file name is“ AGByyyy.tif ”AGB represents the aboveground biomass of grassland, yyyy represents the year; for example, agb2019.tif represents the aboveground biomass of temperate grassland in northern China in 2019.
Data opening method: the annual data in the data set is in grid TIF format, which can be opened directly by ArcGIS software.
