Figure 2 Spatial distribution and proportion of each cropping intensity in the North China Plain for six sub-periods (a−f) since the Qing Dynasty and the accumulated temperature. 1H1Y = one harvest per year, 3H2Y = three harvests in two years, 2H1Y = two harvests per year.
Figure 3 Crop combinations for each crop intensity in the North China Plain. The definitions of 1H1Y, 3H2Y, and 2H1Y are provided in the caption of Figure 2.
