The features and risk of snow-ice disasters in north Xinjiang were researched after analyzing the H and L indexes based on the aggregation, weights and animal husbandry disaster losses of the snow-ice climate events. It was considered that the snow-ice disasters were chain-structured, and the disaster intensity was related to the weights and aggregation degree of snow-ice climate events. Based on the information diffusion theory, the risk of snow-ice disasters was assessed, the snow-ice disasters in north Xinjiang were holistically distributed in a northwest-southeast zonal way, and the occurring frequency of snow-ice disasters in the west, hilly regions and areas with thick snow cover was higher than that in the east, plains and areas with thin snow cover.
