摘要:
基于水文部门提供的常州市雨量站1951~2010年间的逐日降水资料,利用Mann-Kendall 趋势分析法和突变检验法对常州市年降水量、汛期降水量、非汛期降水量和降水日数进行趋势分析和突变检验,并利用Morlet 小波变换法分析常州市年降水量和汛期降水量的多时间尺度周期变化特征。结果表明,年降水量和汛期降水量呈上升趋势,但上升趋势不显著,降水日数呈下降趋势,且下降趋势显著。
Abstract:
Based on the daily precipitation data of Changzhou rainfall station in 1951~2010 from the hydrological department, the trend analysis and mutation test ewre used to analyze the annual precipitation, the precipitation in flood season, the non flood season preciptiation and the number of precipitation days by Mann-Kendall trend analysis method and the mutation test method, and the Morlet wavelet transform method was used to analyze the multi-time scale periodic variaiton characteristics of annual precipitation and flood season precipitation in Changzhou City.The results showed that annual precipitation and flood season precipitation showed an upward trend, but the upward trend was not significant, while the number of precipitation days showed a downward trend, and the downward trend was significant.
