| 摘 要： | 基于上海市徐汇站、宝山站1961年～2019年实测降雨数据,主要采用Mann-Kendall检验和小波分析的方法,对年最大1日降雨序列、年最大5日降雨序列的时程变化和多时间尺度变化规律进行分析.结果表明,城镇化使极值降雨量级增大,城郊极值降雨量变化趋势存在差异.城镇化对最大1日降雨的影响显著高于最大5日降雨,且影响主要...

| Abstract: | Based on measured rainfall data from 1961 to 2019 in Xuhui Hydrologic Station and Baoshan Hydrologic Station in Shanghai,the Mann-Kendall test and wavelet analysis are used to analyze the laws of temporal variation and variation in multi-time scales of maximum one-day rainfall and maximum five-day rainfall during the involved period.It is found that the urbanization causes the increase of extreme rainfall,and there is a difference on variation trend between downtown and suburb.The urbanization has greater impact on variation in multi-time scales of maximum one-day rainfall than that of maximum five-day rainfall,especially on long-period scales.The conclusions of the study contribute to the researches on temporal variation regularity of extreme rainfall considered the urbanization,and boost the integrated construction of Yangtze River Delta Region. |
