摘要: 根据雪冰气候事件的聚合、权重和牧业灾害损失的关系,通过[WTBX]H、L[WTBZ]指数分析,研究了新疆北部的雪冰灾害特征和危险性。研究认为,雪冰灾害具有链状结构,灾害强度与雪冰气候事件权重、聚合度有关。基于信息扩散理论,对雪冰灾害危险性进行分析评估,新疆北部雪冰灾害分布,总体呈西北─东南向带状分布,西低东高,南低北高,低山丘陵高于平原,厚积雪区域高于薄积雪区域。

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.
