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.
