“到城市看海”已成为人人皆知的流行语,这折射出城市内涝问题让人感到有些无奈。为何内涝只发生在城市?这与城市的特点有关,如城市建筑物多、绿地少、路面硬化度高,更与城市生态系统的缺失有关,城市已经到了必须深刻反思治水用水观的关键时期。海绵城市的建设能够缓解以上问题,海绵城市的建设就是要让“城市之肺”正常呼吸,让“城市之肾”正常代谢,城市内涝或许将从根本上得到解决,一个更为完善的城市排水防涝工程系统将建立起来。

Sponge city construction can alleviate the above problems, sponge city construction is to make “city of lung ” breathing normally, “urban kidney ” normal metabolism, city waterlogging may be fundamentally resolved, a more Perfect urban drainage waterlogging engineering system will be established.
