Study on the Ecological Landscape Design of Yawei Creek Wetland Based on LID

In recent years, many cities in China have built sponge cities to cope with the flood disaster faced, and Hainan province has taken the lead in carrying out the "ecological restoration and urban repair" urban double repair pilot work. Based on the LID strategy, take the wetland landscape design of Yawei Creek in Haikou city as an example, wetland landscape ecological design strategies are introduced, including landscape design for water transmission, river channel design, plant planting design and road system design. This paper analyses methods and discusses the urban rain flood management approach, to improve the management level of urban rainwater and provide a good reference for the construction of ecological landscape with regional characteristics in Hainan province.
