青海省1:10万土地利用数据集（2000）

本数据来源于“中国1:10万土地利用数据”。中国1:10万土地利用数据是由中国科学院“八五”重大应用项目《全国资源环境遥感宏观调查与动态研究》组织了中国科学院所属19个研究所的遥感科技队伍，以卫星遥感为手段，在三年内基于Landsat MSS，TM和ETM遥感数据构建的。本数据采用一个分层的土地覆盖分类系统，将全国分为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），31个二级类。这是目前我国精度最高的土地利用数据产品，已经在国家土地资源调查、水文、生态研究中发挥着重要作用。

This dataset is derived from the *China 1:100,000-scale Land Use Data*. It was developed by a team of remote sensing scientists and technicians from 19 research institutes affiliated with the Chinese Academy of Sciences (CAS), organized under the key applied project of the 8th Five-Year Plan (1991–1995) of the Chinese Academy of Sciences: *National Remote Sensing Macro Investigation and Dynamic Research on Resources and Environment*. The dataset was constructed over a three-year period using satellite remote sensing technology, based on Landsat MSS, TM, and ETM remote sensing data. It adopts a hierarchical land cover classification system, dividing the entire country into 6 first-level categories (cultivated land, forest land, grassland, water area, urban, rural, industrial, mining and residential land, and unused land) and 31 second-level categories. It is currently the most accurate land use data product in China, and has played an important role in national land resource surveys, hydrological and ecological research.
