No.3 National-scale 10-m maps of cropland use intensity in China during 2018-2023

There were three groups of national-scale datasets on cropland use intensity over conterminous China during the study period (2018-2023). The first group of datasets was the cropland use intensity dataset for each year. Five 10-m national scale cropland use intensity maps (ChinaCUI10m) were provided for China during 2018-2023. The second group of datasets was the newly derived 10-m cropland dataset (ChinaCropland10m) based on historical cropping activities. The historical cropland use intensity during 2018-2023 was summarized and the ChinaCropland10m was produced through discarding pixels with values of zero (cropland should be actively cropped for at least once during the past five years). The third group of datasets was the degree of intensification revealed by averaged cropland use intensity (ChinaMeanCI10m) based on historical CUI datasets in China during 2018-2023. The datasets are available at the Figshare repository in a Geotiff format. The dataset is provided in ESPG: 4326 (WGS_1984) spatial reference system.

本研究时段（2018-2023年）内，覆盖中国全域的国家级耕地利用强度数据集共有三套。第一套为逐年耕地利用强度数据集：共提供2018至2023年的5幅10米分辨率国家级耕地利用强度影像（ChinaCUI10m）。第二套为基于历史种植活动新生成的10米分辨率耕地数据集（ChinaCropland10m）：研究人员汇总了2018-2023年的历史耕地利用强度数据，通过剔除零值像元（即过去五年内至少发生过一次主动种植行为的耕地）生成了该数据集。第三套为基于2018-2023年中国历史耕地利用强度数据集，通过计算耕地利用强度均值得到的耕地集约化程度数据集（ChinaMeanCI10m）。上述三套数据集均以GeoTIFF（地理标记图像文件格式）存储于Figshare数据仓储平台，空间参考系统采用EPSG: 4326（WGS_1984）坐标系。
