| 摘 要： | 根据北京城郊雨量站1959～2001年逐月降雨资料，分析了北京城市化对降雨特征的影响。分析表明，城市化使北京地区降雨量等值线加密、年雨量增加，使城区雨量变差系数变化大于郊区。分析北京城市化对降雨特征的影响，可为城市雨洪排水工程设计提供参考。

| Abstract: | In accordance with the monthly rainfall data of 1959 to 2001 from the outskirt rainfall stations of Beijing, the impacts from the urbanization of Beijing on the rainfall characteristics therein are analyzed and studied. The results show that the rainfall isogram in the area of Beijing has been densified by the urbanization, and then the annual rainfall has been increased as well; which makes the change of the coefficient of variation of urban rainfall is larger than those of the suburbs. The analysis on the impacts of rainfall characteristics of Beijing can provide a reference for the engineering design of urban rain flood drainage project concerned. |
