No.2 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.

本研究时段为2018-2023年，针对中国全境的耕地利用强度（cropland use intensity）共有三套全国尺度国家级数据集。
第一类数据集为逐年耕地利用强度数据集，包含2018至2023年共5幅10米分辨率全国尺度耕地利用强度图（ChinaCUI10m）。
第二类数据集为基于历史种植活动新生成的10米分辨率耕地数据集（ChinaCropland10m）：研究汇总了2018-2023年的历史耕地利用强度数据，并剔除数值为0的像元（要求耕地在过去5年内至少完成1次主动种植行为），最终生成该数据集。
第三类数据集为基于2018-2023年中国历史耕地利用强度（CUI）数据集，通过平均耕地利用强度表征耕地集约化程度的数据集（ChinaMeanCI10m）。
本系列数据集以GeoTIFF格式存储于Figshare仓储平台，空间参考系统采用EPSG:4326（WGS_1984）。
