摘　　要：以常州市主城区为研究区域,基于高强度降水指数等指标,分析常州市主城区高强度降水特性及其对城市防汛的影响。研究结果表明,受气候变化和城镇化等影响,常州市主城区在1953—2022年期间有雨日数等3个极端降水日数指标、强降水量等6个高强度降水量级指标均呈递增趋势。Taking the main urban area of Changzhou as the research area,based on indicators such as high-intensity precipitation index,this study analyzes the characteristics of high intensity precipitation in the main urban area of Changzhou and its impact on urban flood control.The research results indicate that due to the impact of climate change and urbanization,the urban area of Changzhou City has shown an increasing trend in three extreme precipitation day indicators,such as the number of rainy days,and six indicators of high-intensity precipitation levels,such as heavy precipitation,from 1953 to 2022.
