Abstract: 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.
