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.
