中国长时序耕地种植强度时空分布数据集ChinaCUI(1982-至今)

基于一系列稳健的耕地利用强度（Cropland Utilization Intensity ，CUI）算法，研究团队首次构建出中国长时序耕地种植强度时空分布数据集（ChinaCUI（1982-至今））。包含三个核心子集：1982-1999年的ChinaCUI5km数据集、2000-2017年的ChinaCUI500m数据集，以及2018年以来的ChinaCUI10m数据集。数据集均使用ESPG: 4326（WGS_1984）坐标系，包含四个数值类别，分别对应：[0：休耕，1：一年一熟，2：一年两熟，3：一年三熟]。该长期年度数据集的建立，不仅有效填补了现有数据空白，更为结合历史种植实践制定针对性农业管理策略提供了坚实的数据支撑。

Based on a series of robust Cropland Utilization Intensity (CUI) algorithms, the research team has for the first time developed the China long-term time-series cropland planting intensity spatiotemporal distribution dataset, ChinaCUI (1982–present). It comprises three core subsets: the ChinaCUI5km dataset covering 1982–1999, the ChinaCUI500m dataset covering 2000–2017, and the ChinaCUI10m dataset since 2018. All datasets adopt the EPSG:4326 (WGS_1984) geographic coordinate system, and include four numerical categories corresponding to: [0: fallow, 1: single cropping per year, 2: double cropping per year, 3: triple cropping per year]. The establishment of this long-term annual dataset not only effectively fills existing data gaps, but also provides solid data support for formulating targeted agricultural management strategies based on historical cropping practices.
