Grassland productivity on the Qinghai-Tibetan Plateau since 1980


The data set includes the spatial distribution of grass yield in the Qinghai-Tibetan Plateau in 1980, 1990, 2000, 2010, and 2017. The gross primary productivity (GPP) of grassland in the Qinghai-Tibetan Plateau was simulated based on the ecological hydrological dynamic model VIP (vegetation interface process) with independent intellectual property of Institute of Geographical Sciences and Natural Resources Research, Chinese Academy of Sciences. The net primary productivity (NPP) was estimated by empirical coefficient, and converted it into dry matter, and then the hay yield was estimated by root-shoot ratio. The spatial resolution is 1km. The data set will provide the basis for grassland resource management, development, utilization and the formulation of the strategy of "grass for livestock".


Data file naming and use method

File name: the grass yield data is stored in ASCII file. The file name is "agb_yyyy. asc", where yyyy represents the year. For example, agb_2000 represents this ASCII file to describe the grass yield of the Qinghai-Tibetan Plateau in 2000.
Data reading mode: all ASCII files in the data set can be directly opened with a text program (such as Notepad). Except for the header file, the main content is the numerical representation of the grass yield. If you want to display it with a diagram, you can open it with ArcGIS. During the reading process, a grid file will be generated. The displayed grid file is the graphic representation of the ASCII file.
