本数据集为2021-2022年黄土丘陵沟壑区第一副区裴家峁沟流域下垫面观测数据集。数据集基于2021、2022年“高分一号”卫星遥感影像，利用ARCGIS软件进行遥感影像解译，辅以实地调查的方法对解译图斑的属性和边界逐一核实修正。本数据集包括裴家峁沟流域土地利用现状表和裴家峁沟流域土地利用专题图、下垫面调查报告。

The remote sensing images are interpreted by ArcGIS software, supplemented by field investigation, and the attributes and boundaries of the interpreted spots are verified and corrected one by one. This data set includes the land use status table of peijiamaogou watershed, the thematic map of land use of peijiamaogou watershed and the underlying surface investigation report

Based on the fusion remote sensing image with spatial resolution of 2m, combined with the remote sensing image interpretation marks established by field investigation, the land use types such as dam land and terrace in the basin are extracted by manual visual interpretation using ArcGIS software platform.
