2021-2022年黄土丘陵沟壑区第一副区韭园沟流域下垫面观测数据集

本数据集为2021-2022年黄土丘陵沟壑区第一副区韭园沟流域下垫面调查数据集。本数据集基于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。本数据集共包括韭园沟流域土地利用现状表、韭园沟流域土地利用专题图、下垫面调查报告。

This dataset is the underlying surface investigation dataset of the Jiuyuangou Watershed in the first sub-region of the Loess Hilly and Gully Region during 2021-2022. It is developed based on the remote sensing images of the Gaofen-1 Satellite in 2021 and 2022. Remote sensing image interpretation was conducted using ARCGIS software, and the attributes and boundaries of each interpreted image patch were verified and corrected one by one with the aid of field investigations. This dataset includes the current land use status table of the Jiuyuangou Watershed, the land use thematic map of the Jiuyuangou Watershed, and the underlying surface investigation report.
