中国1km网格土地利用数据(2000年)

针对资源环境和全球变化研究领域以及国家宏观经济决策和重大开发举措的实施对定量的空间型社会经济数据的需求，建设了具有统一空间坐标参数、统一数据格式、统一的数据和元数据标准的中国1公里格网土地利用数据库，以满足科学研究和政府定量化科学决策的需要。每个1KM×1KM格网带有耕地（水田、旱地）、林地、园地、草地、城镇居民点用地、工矿用地、交通用地、未利用地等的面积比例。

To address the demand for quantitative spatial socio-economic data from the research fields of resource environment and global change, as well as for national macroeconomic decision-making and the implementation of major development initiatives, a 1-kilometer grid land use database of China has been developed. The database adopts unified spatial coordinate parameters, uniform data format, and consistent data and metadata standards to meet the requirements of scientific research and quantitative scientific decision-making by the government. Each 1 km × 1 km grid includes the area proportions of arable land (paddy fields, dry land), forest land, garden land, grassland, urban residential land, industrial and mining land, transportation land, unused land, and other land use types.
