摘　　要：土壤保持能力是评价生态系统服务功能的重要指标之一,在维护区域生态安全中具有重要作用。本数据集包含了三北工程区2000–2020年生态系统土壤水蚀模数和土壤保持量的空间分布数据。这些数据是以三北工程区的遥感、气象、地理和土壤等多源数据为基础,结合GIS技术,利用RUSLE模型进行的估算,直观地评价了三北工程区2000–2020年生态系统土壤保持能力。本数据集从数据来源和模型计算等两个方面进行了数据质量控制,以保证数据的客观准确性,可为三北工程区生态系统土壤保持服务变化评价及生态系统服务变化评价提供必要的科学依据。Soil conservation capacity is one of the most important indicators for evaluating the ecosystem functions and services and 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 the Three-North Shelter Forest Programme from 2000 to 2020.This dataset evaluated the soil conservation capacity of the Three-North Shelter Forest Programme from 2000 to 2020 directly based on the multiple data sources of remote sensing,meteorology,geography and soil,using GIS technology and RUSLE model for estimation.In order to ensure the objectivity and accuracy of the data,quality control was established in two aspects:data source and model calculation.This dataset could provide valuable scientific foundation for evaluating the changes of soil conservation service function and ecosystem functions and services in the Three-North Shelter Forest Programme.
