Design Of Urban Park Planning Based On Stormwater Management

Stormwater Management is through the process of rainwater collection,detention,purification,and infiltration to achieve the purposes of flood prevention,drainage,and reuse of rainwater resources,especially in urban detention areas,using detention parks to integrate rainwater management measures and urban comprehensive park construction methods,while ensuring the safety of floods to promote the ecological construction of urban parks.This article uses Shenzhen Honghu Park as the research object.In the context of Luohu District renewal and sponge city planning,this paper explores the design method of urban parks based on stormwater management.It is hoped that from the perspective of landscape architecture,it will maintain the safety of urban rain floods,reorganize rain water resources,optimize the landscape features of urban flood storage and detention areas,and explore the detention park landscape design methods that have both flood prevention and recreational functions.This article aims to explore the design methods and main points of urban parks under stormwater management.First,by sorting out related researches on stormwater management,detention parks,and urban detention areas,including basic theory and related engineering technology,and concept features and functional classification of detention parks.Apply the design points to the design practice of Shenzhen Honghu Park,put forward the design concepts of ensuring water safety,restoring water ecology,constructing water landscapes and sharing water leisure,and summarize the design steps of the detention park.First,clear the flood flooding inundation scope and divide the flood control level.Then configure plants with different water and humidity resistance,construct ecological revetments and repair the water ecological environment,and build suitable landscapes.According to the actual runoff characteristics,rainwater and flood facilities are arranged for rainwater flood regulation and storage.Finally,the functional zoning is reasonably arranged in combination with stormwater safety andrecreational safety to meet the multiple needs of the complex functions of the park,in order to explore the current ecological approaches and methods of urban flood prevention and drainage and the harmonious development of landscape construction.It is concluded that the urban flood and waterlogging problem relies on multidisciplinary comprehensive technologies,laws and regulations and other policies.The construction of the urban detention park system should be based on actual flood and waterlogging problems.The flood control function of the detentiom park should be exerted through landscape techniques to gradually solve the rainwater flood storage and adaptive landscape,water ecological purification and leisure and recreation issues.
