摘要
基于华东地区安徽省池州市贵池雨量站共计69年的逐月降水资料,采用多种降水变化及突变分析法进行分析研究。结果表明:池州市69年的降水量从整体来看具有非显著性增加的趋势,从年际序列观察可以发现四季中除春季未发生突变,其他季节均有个别年份发生了突变。
Based on the monthly precipitation data of Guichi rainfall station in Chizhou City, Anhui Province in East China for 69 years, a variety of precipitation change and catastrophe analysis methods are used to analyze and study. The results show that the precipitation of Chizhou City in 69 years shows a non significant increase trend from the overall observation. From the interannual sequence observation, it can be found that there is no mutation in the four seasons except spring, and there are mutations in individual years in other seasons.
