Research on Landscape Stormwater Management Planning Strategy in Floodplain Based on NbS
In recent years,a growing body of research has demonstrated that incorporating nature-based solutions(NbS)into communities enhances disaster risk resilience.As a widely distributed outdoor space,landscape public space can effectively control source pollution.However,how to integrate stormwater management solutions into the landscape public space in the form of planning,and play the multiple benefits of the local ecosystem in the form of beauty is an urgent problem.This paper summarizes the connotation of NbS,expounds the characteristics of landscape stormwater management planning under NbS,and collects typical cases at home and abroad on how to use NbS measures to solve flood problems,water quality problems and ecological problems.Combined with the characteristics of flood plains,a planning method based on"ecosystem vulnerability analysis-landscape stormwater management planning under NbS-landscape planning scheme assessment-operation and maintenance"is proposed,and the prospect and obstacles of implementing this scheme in the future are also presented.
