中国生态、居住、与工业土地利用空间数据集(2008)

以土地的主体功能为出发点，将中国土地利用划分为生态、生活（居住）、生产（工业）（即“三生”用地）功能类型。中国“三生”用地数据集由二级数据组成，第一级划分4种类型，即：生态用地、生态生产用地、生产生活用地、生活生产用地，它体现了土地的主体功能和次要功能的方向。第二级在第一级基础上，划分了16种类型，它们分别是：生态容纳用地、河岸防护用地、土壤保持用地、水源涵养用地、洪水调蓄用、防风固沙用地、生物多样性保护用地、一般调节用地、渔业养殖地、牧草地、园地、用材林地、耕地、城镇建成区用地、农村生活用地、工商生产用地。第二级土地利用分类是第一级分类的进一步细化，主要明确土地能够提供的具体服务功能及其重要程度。

Starting from the dominant functions of land, China's land use is categorized into three functional types: ecological, living (residential), and production (industrial), collectively referred to as "production-living-ecology" (三生) land use. China's "Three-Type" (三生) Land Use Dataset consists of a two-tier classification system. The first-level classification includes 4 types: ecological land, ecological-production land, production-living land, and living-production land, which reflect the dominant and secondary functional orientations of the land. The second-level classification, based on the first-level classification, divides land use into 16 subtypes, namely: ecological accommodation land, riparian protection land, soil conservation land, water conservation land, flood storage and regulation land, windbreak and sand fixation land, biodiversity conservation land, general regulation land, fishery aquaculture land, pasture land, garden land, timber forest land, cultivated land, urban built-up area land, rural residential land, and industrial and commercial production land. The second-level land use classification is a further refinement of the first-level classification, which primarily clarifies the specific service functions that the land can provide and their respective importance levels.
