摘    要:在介绍济南市城市化发展水平及暴雨特性的基础上,选用济南市黄台桥、燕子山、东红庙、吴家铺和刘家庄雨量站1977-2007年汛期降雨资料,通过趋势线、距平统计、双累积曲线等方法,对济南市区汛期降雨量进行了统计分析,并对济南市城区、郊区的降雨时空特征进行对比研究。研究结果表明,城区多年汛期降雨量表现出较强的波动性,但整体上升趋势较为明显,尤其是改革开放早期的降雨量增长较为迅速。城市化对济南城区产生了较为明显的雨岛效应,城区比郊区降雨量增加约10%。城市化对降雨的频次以及雨型均造成了较大的影响,增加了各种降雨强度等级的降雨机率,城区比郊区的降雨机率增加10%以上,特别是暴雨以上的降雨场次增加了22%。

关 键 词:城市化  降雨特征  汛期  济南市

Abstract:Long-term precipitation series covering 1977-2007 at the Huangtaiqiao,Yanzishan,Donghongmiao,Wujiapu and Liujiazhuang stations in Jinan City were systematically analyzed with aim to demonstrate impacts of urbanization on the precipitation patterns in both time and space.In the current analysis,linear regressive technique,anomaly departure analysis,double cumulative mass-curves were applied and comparison was performed between precipitation changes in the urban proper and suburban areas in the Jinan City.The...
Keywords:urbanization  precipitation features  flood period  Jinan City
