【 摘 要 】

Taking a residential area as example, this paper introduced the designing strategies for the Sponge City Design Project in Tianjin. The geographical conditions, rainfall characteristics, the underlying surface conditions, vertical conditions, and drainage systems were analyzed to select the suitable low-impact development measures. It was found that the green lands, permeable pavements, and rainwater buckets had met the requirements for the control of total annual runoff, surface-source pollution control, and rainwater reuse required by the eco-city. The construction of the Sponge City Rainwater System will not only allow the building community to meet the evaluation criteria for green buildings and green communities, but also gain government support, increase the social awareness of construction developers, and increase social benefits. In addition, the Sponge City Rainwater System also brings good ecological benefits to real estate projects.
