This data is used by the research team to quantitatively evaluate the ecosystem water yield of the Qaidam Basin from 1980 to 2018 by using the invest model based on the data of land use, meteorology, soil, topography, etc. of the Qaidam Basin. Based on the water yield, the water conservation capacity is evaluated by comprehensively considering the factors such as soil permeability, surface runoff difference of land types and land shape. The spatial resolution is 1km, and the unit is mm.
Land use data, meteorological data, soil data and topographic data.
Based on the land use data of the Qaidam Basin, combined with meteorological data, soil data, topographic data, etc., the water yield module of the invest model is used to quantitatively evaluate the water yield of the Qaidam Basin from 1980 to 2018, and the water conservation capacity is evaluated based on the water yield by comprehensively considering the soil permeability, the surface runoff difference of different types and the terrain.
According to the annual average total runoff of the Qaidam Basin in the Qinghai water resources bulletin, after deducting the glacier recharge, the Z value is determined by comparing the simulation results of the annual water production of the Qaidam Basin from 1980 to 2018. Through error calculation, it is found that the simulation results of the invest model for water production are relatively accurate, and the relative error is less than 5%. Based on the water yield, the water conservation capacity is evaluated by comprehensively considering the factors such as soil permeability, surface runoff difference of land types and topography.
