三北工程区生态系统土壤保持能力评估数据集（2000–2020年）

Soil Conservation Capacity is a key indicator for evaluating the ecosystem service function, which plays an important role in maintaining regional ecological security. The dataset includes the spatial distribution data of soil erosion modulus and soil conservation amount in sanbei project area from 2000 to 2020. Based on the multi-source data of remote sensing, meteorology, geography and soil, and combined with GIS technology, RUSLE model was used to estimate soil erosion modulus and soil conservation capacity to evaluate the soil conservation capacity of the study area. In order to ensure the objective accuracy of the data, the data quality control is carried out from two aspects: data source and model calculation, and the soil conservation capacity of sanbei project area ecosystem from 2000 to 2020 was directly evaluated. The dataset can provide valuable scientific foundation for evaluating the changes of soil conservation service function and ecosystem service function in sanbei project area.
