摘　　要：目的冰雹是一种局地范围的灾害性天气,宝鸡渭北地区冰雹灾害非常严重,对农业生产危害极大。根据宝鸡渭北地区冰雹分布及地理环境的特征,分析了地形地貌、植被、土壤对冰雹的影响机理,提出了相应的减灾对策。方法将冰雹发生频率与地理环境进行对比分析。结果下垫面的热力非均匀性是冰雹强度增加的主要因素。结论根据当地情况,提出了加强预测预报、植树造林和改良土壤以及减弱上游冰雹形成因素的对策。Aim The hail is a kind of the calamity weather of local range. Hail disaster is very and have great harmful to agricultural production in the north of Weihe in Baoji, Shaanxi, China. Bases of the distribute and characteristic of geographical environment, it was analyzed that the topography , vegetation ,and soil mechanism of impact on hailstorm, and the corresponding countermeasures of reducing hail disasters were given.
