| 摘 要： | 利用宝鸡30年(1971～2000年)夏季(6～8月)降水资料，采用正态化Z指数变换和谐波分析方法对宝鸡降水进行了旱涝等级划分及时间演化规律研究。结果表明：宝鸡地区不同级别平涝出现的几率存在着一定的差异，旱涝具有明显的年际、年代际、周期性以及阶段性和群发性变化特征。

| Abstract: | The annual and month precipitation data in June, July and August of Baoji during 1971 to 2000 were analyzed with Z index according to the Person I distribution and harmonic wave analysis methods, the features of summer drought and flood in Baoji were studied. The results show that the summer drought and flood are of obvious characteristics of periodic change,interannual and interdecade variation,and group occuring. The probabilities of different droughts and floods in Baoji are different. |
