N0.2 ChinaCUI: Long-term Spatiotemporal Distribution Dataset of Cropland Cultivation Intensity in China (1982–Present)

This dataset is developed based on a series of robust Cropland Utilization Intensity (CUI) algorithms, enabling the automatic acquisition of large-scale agricultural cropping pattern information. For the first time, it establishes the long-term spatiotemporal dataset of cropland cultivation intensity in China—<b>ChinaCUI (1982</b><b>–</b><b>present)</b>. The dataset consists of three core subsets: <b>ChinaCUI5km (1982</b><b>–</b><b>1999)</b>, <b>ChinaCUI500m (2000</b><b>–</b><b>2017)</b>, and <b>ChinaCUI10m (2018</b><b>–</b><b>present)</b>.The establishment of this long-term annual dataset not only effectively fills the gap in existing data resources but also provides strong support for formulating targeted agricultural management strategies informed by historical cropping practices. The dataset is provided using the <b>EPSG:4326 (WGS 1984)</b> spatial reference system.本数据集基于一系列稳健的耕地利用强度（Cropland Utilization Intensity, CUI）算法开发而成，可自动获取大规模农业种植格局信息。本数据集首次构建了中国耕地种植强度的长期时空数据集——**ChinaCUI（1982年至今）**。该数据集包含三个核心子数据集：**ChinaCUI5km（1982年—1999年）**、**ChinaCUI500m（2000年—2017年）**以及**ChinaCUI10m（2018年至今）**。此长期逐年数据集的构建，不仅有效填补了现有数据资源的空白，更为依据历史种植实践制定精准化农业管理策略提供了有力支撑。本数据集采用**EPSG:4326（WGS 1984）**空间参考系统进行发布。
