摘　　要：统计分析了1956年以来以来广西冰雹的时空分布特征及影响因子,并提出了减灾对策。广西冰雹集中在2～5月,主要发生在14～19时;北多南少,西多东少,山区比沿海多;大范围冰雹过程可分为高原东部深槽型;南支槽型;华北深槽型。其中南支槽是冰雹天气的最主要系统;冰雹次数与拔海高度正相关,与年平均气温负相关。We statistically analyze the spatial and temporal distribution characteristic and impact factor of hail in Guangxi since 1956,and put forwards a proposal about mitigation measures.The hail of Guangxi is concentrated on February-May,and mainly happen at 14～19 o＇clock.The hail happens in the north is more than that in the south and the west is more than that in the east,while that happens at the mountain area is more than that in the east coastal.The reason that cause large-scale hail can be divided into three types ： a deep trough at east of a plateau,a trough in the south,a deep trough at North China.The trough in the south is the main system that causes hail.The times of hail happening is positive correlate with sea level,and is negative correlated with the annual mean temperature.
