Abstract: ABSTRACT Climate change brings extreme weather and precipitation heterogeneity, which seriously threatens the agricultural ecosystem and food security, and increases the difficulty of agricultural risk management. This study, the potato in the northern single cropping area was taken as the research object, quantitatively assessed potato drought disaster risk based on the four-factor theory of natural disaster risk formation. The results show that; (1) The hazard and vulnerability show opposite trends in space; (2) The exposure decreases from the middle to the east-west direction; (3) Cross distribution of high and low values of disaster prevention and mitigation capabilities; (4) The areas with extremely high and high risks drought disasters are mostly located in the central and southeast regions of the study, and the risk changes at all levels show different trends in numerical values. The non-overlap of high-yield areas, high adaptability areas and main planting areas is currently the main problem faced by the northern single cropping area. To develop potato industry, we must pay attention not to blindly expand the planting area, but to neglect the improvement of agricultural productivity, scientific layout and the prevention of increasing agrometeorological disasters.
