摘要
城市雨水总量控制是海绵城市建设过程中的重要指标之一,对于促渗减排、涵养水源、维护区域水生态至关重要。但是,目前对于城市雨水总量控制的理解存在概念上的混乱和理解误区,结合美国城市雨水径流管理的发展历程,分析了城市雨水径流总量控制的必要性、总量控制参数及特点,并选择我国8个典型城市近30年的降雨资料作为统计样本,比较了不同统计方法对应的设计降雨量的差别,以期为我国海绵城市建设过程中城市雨水总量控制指标的选择提供科学依据。
The total volume control of urban rainwater is one of the important parameters during sponge city development. It is important to promote the permeability, water resource conservation, water ecological maintenance. However, there exist confusion and erroneous for the rainfall total volume control method. Combined with the development of American urban stormwater runoff management, the necessity of urban rainwater total volume control, different total volume control parameters and characteristics were analyzed. The rainfall data of eight typical cities in nearly 30 years in China was taken as the statistical sample. And then, the results from different statistical methods were compared so as to provide the basis for the rainfall total volume control in sponge city.
