摘　　要：随着城市化进程的不断加快,城市水文过程发生着剧烈的变化,深入研究城市地区的水文变化规律及城市发展对水文特性的影响过程,可以为城市降雨径流的模拟计算提供理论支撑,结合武汉市汉阳区十里铺的特点,在充分了解其地表产汇流机理和过程的基础上,利用水文学、水力学等知识,构建了城市降雨径流计算模型。由于本次地表产汇流采用了几种方法,故分别进行了组合,得到不同组合下十里铺小区的城市降雨径流计算模型;结合收集到的实测降雨和排水流量资料,对模型进行参数率定及验证;结果表明,本次所建的模型结构是合理的。With the accelerating urbanization process, the hydrological processes change sharply. Studying the rules and characteristics of ur-ban hydrology change further can provide a theoretical support for their simulation and calculation. On the basis of understanding the mecha-nism and process of the runoff generation and confluence fully, and by using the knowledge of hydrology and hydraulics, the urban rainfallrunoff model is built by combining the characteristics of Shilipu District in Hanyang, Wuhan. Due to the methods used in runoff generationand confluence, different models are obtained by different combination and all models are calibrated and verified. The results show that themodels buih are reasonable.
