重大生态工程的实施会导致土地利用的广泛变化，从而影响区域生态系统服务功能。为探索1999-2020年黄土高原退耕还林工程实施区域的时空格局和趋势变化，在考虑中国行政区划的基础上，构建了黄土高原县域数据集。其中，利用ArcGIS软件对土地利用年度数据进行提取和处理，得到1999-2020年黄土高原各县（区）年度GGP实施面积数据，包括7种土地利用转换类型，数据总量为179.1MB。该数据集为黄土高原生态环境的保护与管理提供了理论依据，为区域GGP项目的实施提供了数据支持。

The implementation of major ecological projects can lead to extensive land use changes, thereby affecting regional ecosystem service functions. To explore the spatial-temporal patterns and trend changes in the implementation area of the ‘Grain for Green’ Project (GGP) on the Loess Plateau from 1999 to 2020, this dataset was constructed at the county level, taking into account China's administrative divisions. Specifically, annual land use data were extracted and processed using ArcGIS software, resulting in the annual GGP implementation area data for each county (district) on the Loess Plateau from 1999 to 2020, including seven types of land use conversions, with a total data volume of 179.1MB. This dataset provides a theoretical basis for the protection and management of the Loess Plateau's ecological environment and offers data support for the implementation of regional GGP projects.
