北京是一座古老而充满活力的城市,她具有3000多年的建城史和800多年的建都史,而今又是全国政治、文化和国际交往中心。50多年来北京城市水利建设取得了巨大成就,建立了比较完整的城市防洪排水体系及城市供水系统,改善了城市水环境,为城市发展及社会安定发挥了重要的作用,也为北京这座历史文化名城增添了绚丽的光彩。在北京城市化发展的同时,也出现了城市防洪排水能力不足、水资源供需矛盾尖锐,城市水环境遭受破坏等问题。这些问题反过来又制约了城市的发展,并将成为21世纪城市面临的巨大挑战。
Beijing is an ancient and vibrant city. With over 3,000 years of history of urban construction and more than 800 years of history, Beijing is now the political, cultural and international center of the nation. Over the past 50 years, great achievements have been made in urban water conservancy construction in Beijing, a relatively complete urban flood control and drainage system and urban water supply system have been established, urban water environment has been improved, and urban development and social stability have been played an important role. Cultural city adds gorgeous glory. At the same time of the urbanization in Beijing, there are also problems such as insufficient urban flood control and drainage capacity, sharp contradiction between supply and demand of water resources and destruction of urban water environment. These problems, in turn, constrain the development of the city and will be a great challenge for cities in the 21st century.
