- Abstract:
- In order to control waterlogging and non-point source pollution risks caused by urban rainfall runoff, and to guarantee urban drainage safety and water environment quality, the definition, types and functions of non-structural measures for urban stormwater low impact development (LID) were elaborated regarding the disaster reduction terminology developed by United Nations office for disaster risk reduction (UNDRR). The application of LID non-structural measures in different sponge city construction stages was analyzed. The results showed that the sponge city construction could be promoted by LID non-structural measures through policies, laws, economy and public awareness promotion. LID non-structural measures could guide the planning and design and provide financing methods, so that the supervision, management, operation and maintenance of structural measures would be guaranteed. However, non-structural measures are still faced with implementation obstacles such as difficulty in quantifying their effects and uncontrollable targets at present, and the focus of sponge city construction will gradually shift to LID non-structural measures in the near future.
