Fig. 3: Model-based simulation of land-use suitability during the late Tang Dynasty.

From: Hydroclimatic instability accelerated the socio-political decline of the Tang Dynasty in northern China

Fig. 3

Light green polygon refers to the Tang Dynasty crop production area82. Land-use potential are the accumulative scores of soil properties98,99, topography and climate variables91. The intensity corridors show the highest probability of transportation pathways towards each prefecture center. The bar plot shows the suitability score distribution in percent. Agricultural potential is generally above mean value of 0.5 across the late Tang Dynasty productivity zone (normalized standard scores from 0 to 1; reference period of the climate variables is 1980–2018 CE. Tang towns and prefecture data acquired from CHGIS104,105 (refer to Fig. 1 and Table S1 for site names; see Fig. S13 for data distribution in each prefecture and Fig. S14 for the entire catchment).
