张掖市土地利用/土地覆盖数据集(2005年)

本数据集来自中科院寒旱所颜长珍等人完成的张掖市2005年土地利用数据集。该数据采用一个分层的土地覆盖分类系统，有6个一级类（耕地、林地、草地、水域、城乡、工矿、居民用地和未利用土地），25个二级类，覆盖甘肃省张掖市五县一区，据范围覆盖全部张掖市。

This dataset originates from the 2005 land use dataset of Zhangye City, which was developed by Yan Changzhen et al. from the Cold and Arid Regions Environmental and Engineering Research Institute (CAREERI) of the Chinese Academy of Sciences (CAS). It adopts a hierarchical land cover classification system, including 6 first-level land cover categories (farmland, woodland, grassland, water area, urban-rural industrial and residential land, and unused land) and 25 second-level land cover categories. The dataset covers five counties and one district under the jurisdiction of Zhangye City, Gansu Province, with its coverage spanning the entire administrative region of Zhangye City.
