柴达木盆地产水量和水源涵养量数据集（1980-2018年）

本数据是研究团队利用柴达木盆地土地利用、气象、土壤、地形等数据，采用InVEST模型定量评估柴达木盆地1980-2018年生态系统产水量，基于产水量综合考虑土壤渗透性、地类的地表径流差异和地形等因素评估水源涵养量，空间分辨率为1km，单位为mm。

This dataset was developed by a research team, which utilized multi-source data including land use, meteorological, soil, topographic and other relevant data of the Qaidam Basin. The team employed the InVEST model to quantitatively assess the ecosystem water yield of the Qaidam Basin over the period from 1980 to 2018. Based on the obtained water yield results, the water conservation capacity was evaluated by comprehensively incorporating factors such as soil permeability, differences in surface runoff among different land use types, and topography. The spatial resolution of this dataset is 1 km, with the unit being millimeter (mm).
