利用宝鸡地区1960—2010年逐日降水资料，对宝鸡地区暴雨、大暴雨进行时空分布特征分析。结果表明，其年际和年代际变化均呈波浪型，20世纪60和90年代为谷值，20世纪70—80年代和21世纪00年代为峰值，特别是21世纪以来暴雨日数明显增多。宝鸡地区的暴雨具有明显的季节性特征，夏季暴雨最多，尤以7月为最；多局部暴雨，少大范围暴雨。暴雨南北山区多，东部塬区少；而大暴雨东北部塬区多，川道和南部山区少。

Using daily precipitation data of Baoji area from 1960 to 2010, spatial-temporal distribution of rainstorm and heavy rainstorm in Baoji was ana-lyzed. The results showed that inter-an-nual and decadal changes of the rainfall were both wave lines, achieved the val-ley value in the 1960s and 1990s, and the peak value in the 1970s, 1980s and 2000s, especially rainstorm days in-creased greatly in the twenty-first cen-tury. Rainstorm in the local area showed obvious seasonal characteristics, oc-curred most in summer, especially in July; most of them were local, and less widespread; rainstorm occurred more in southern and northern mountainous ar-eas, and less on eastern highland; heavy rainstorm occurred more in northeastern highland, less in river basins and south-ern mountainous areas.
