Abstract:: From three aspects:hazards risk, vulnerability of carrier, disaster prevention and resilience, we evaluated the rainstorm disaster under the influences of ENSO in the border area of Shaanxi, Gansu, Ningxia and Inner Mongolia from the macro, meso and micro scales. The results show that:(1) northwest fragile zone rainstorm disasters and Lanina events showed a strong correlation at macro, meso, micro scales; (2) the hazard risk, vulnerability of carrier, disaster prevention and resilience have a strong regional differences, the hazard risk and distribution of rainfall showed a consistent feature, it gradually reduced and showed obvious zonal distribution features from southeast to northwest; the regions with the highest vulnerability of carrier mainly include the Tengger Desert of Jingtai, Alxa Left Banner and Minqin of Gansu; the highest regional in disaster prevention and resilience are Changwu, Yan’an, Wuqi and Pingliang; (3) because of rainfall characteristics and terrain factors, the highest risk areas of storm disaster are Yulin, Xifeng, Pingliang, Changwu and other areas.
