Strategy Of Campus Green Space Renovation Based On Chenghong Resilience

With the rapid development of urbanization in China,global climate problems become more and more acute,extreme weather frequently patronizes,and the ability of cities to resist rain and flood disasters is becoming increasingly low.Especially in the old city with old infrastructure,university campus,as the basic unit of a city,also suffers from the same problem.Frequent waterlogging disasters have seriously affected the study and work of the campus staff and students,and also caused great damage to the campus landscape.Based on this background,this paper analyzes and summarizes the research on the resilience of flood carrying capacity at home and abroad,puts forward the constituent elements of campus space environment,and establishes the related framework between the sub elements of campus space environment and the resilience of flood carrying capacity.At the same time,combined with typical cases at home and abroad,it summarizes the strategies and methods to effectively enhance the resilience of flood carrying capacity,so as to build the resilience of campus green space System.Taking Wenhua Road Campus of Henan Agricultural University in the old urban area of Zhengzhou as the research case,the storm flood management model(SWMM)software is selected to model the flood carrying status and optimization measures of the selected target campus,and run the simulation analysis.The average runoff depth.total drainage,runoff coefficient and drainage coefficient of the campus under different rainstorm return periods are analyzed Peak value and other data are compared and analyzed to verify the renewal and transformation strategy proposed in the previous paper to enhance the resilience of the old campus.It has a certain practical significance and reference value for the existing problems such as rain and flood disasters and the old campus which needs to improve the flood carrying capacity and landscape environment quality.
