南阳市位于河南省西南部,是中部地区重要的交通枢纽,豫鄂陕三省交界地区的区域性中心城市和生态宜居城市。近年来,南阳市抓住南水北调中线工程建设、筹备召开全国农运会等战略机遇,不断完善城市基础设施,高新产业集聚、人口增长,城市规模不断扩大。但是,城市系统更加复杂化,也愈发脆弱。频发的洪涝灾害就是南阳市所面临和必须解决的问题之一。文章针对南阳市中心城区防洪排涝存在的问题,按照洪水资源化、海绵城市建设理念,提出了应对洪涝灾害的工程及管理措施。
Located in southwestern Henan Province, Nanyang City is an important transportation hub in the central region, a regional central city at the junction of Henan, Hubei and Shaanxi provinces and an ecologically livable city. In recent years, Nanyang City has seized the strategic midline project of South-to-North Water Diversion, prepared for the convening of such strategic opportunities as the National Peasant Sports Games, and continuously improved urban infrastructure, high-tech industries, population growth and the city’s scale. However, the urban system is more complicated and vulnerable. Frequent floods are one of the problems facing Nanyang City and must be solved. According to the existing problems of flood control and drainage in the downtown area of Nanyang City, this paper puts forward the engineering and management measures to deal with flood disasters in accordance with the concept of flood recycling and sponge city construction.
