Maps of cropping patterns in China during 2015-2021

Here we present the first annual 500-m maps of multiple cropping systems in china at national scale during 2015 to 2020,which provide information on cropping intensity with descriptions of three staple crops (Maize,paddy rice and wheat). We produced the cropping patterns maps by developing phenological metrics, which can be applied to national scale.

本研究首次发布了2015至2020年中国国家尺度下多熟种植制度的500米分辨率年度制图数据。该数据集涵盖玉米、水稻、小麦三种主粮作物的种植强度相关信息。本研究通过构建物候指标（phenological metrics）生成了可适用于国家尺度的种植格局制图产品。
