Abstract
With global climate change and accelerated urbanization, floods are increasing globally in frequency and intensity each year. In the past, urban flood control was mainly based on resilience, but hard embankments destroyed the ecological environment around and cannot meet the sustainable development needs of new cities anymore. The application of resilience theory in urban flood control has received extensive attention. This paper applies the concept of resilient flood bearing to the study of urban waterfront space with the goal of urban flood control. As a land-water confluence area, the waterfront space not only shoulders the responsibility of connecting the entire land ecosystem, but also carries functions such as leisure and entertainment, cultural science popularization, and economic development. It is of great significance to urban ecology, residents' lives, flood prevention and disaster reduction. First, this paper summarizes and compares the theoretical studies related to flooding and resilient flood-bearing. On this basis, the article emphasizes the construction of a resilient flood-bearing system for waterfront spaces by combining landscape architecture, and explores scientific and feasible resilience strategies in four aspects: ecological, engineering, social and economic. The article selects Tangyangzhou Park in Changsha as the research site and introduces HEC-RAS software to simulate the inundation condition of the site when flooding strikes. The paper uses quantitative data to assist qualitative analysis to guide the planning and design, and proposes a landscape resilience flood-bearing system for urban waterfront spaces based on the simulation results and preliminary research. The study proposes strategies for urban flood protection through multidisciplinary cooperation and the introduction of new technologies, hoping to provide a reference for future urban resilience construction.
