A Study On The Landscape Reconstruction Design Of The Xingye Avenue Based On The Sponge City Theory

Under the background of rapidly changing research on the new concept of sustainable urban water management,the original rainwater management system cannot match the growing demands for water resources all over the world,so the transformation of the rainwater management system is setting off an upsurge around the world.This paper associates the actual design case of landscape reconstruction of Xingye Avenue,High-tech Zone,Heyuan City with the concept of planning a sponge city.Through the study on the literature at home and abroad,the author knew the latest news and research content on the development of sponge city of the times and concluded the research theories and methods applicable to this paper.The sponge city is of great significance and practicality to the economic and social development in China.The key is to choose suitable pavement to enhance the penetration ability,carry out the reasonable design of greening to improve the absorption and discharge of rainwater,and finally utilize the landscape pieces properly to strengthen the rainwater regulation ability according to local conditions and people-oriented principle.After an overall description of the historical background,policy orientation,and general summary of Xingye Avenue,an on-site survey was implemented for Xingye Avenue,High-tech Zone,Heyuan City.It is to know the causes of the current situation of Xingye Avenue and its future development space,and then conduct the on-site survey on the current interface along the street,pavement,street greening,landscape pieces of Xingye Avenue and record their images.The questionnaire survey and case analysis were adopted to analyze the rainwater regulation ability according to the survey results.This paper analyzes the combination of the transformation of Xingye Avenue and the concept of sponge city as well as the actual application from the perspective of the full use of existing topography,the reasonable construction of permeable roads,the functional configuration of greening,and the supplementary ecological functions of landscape pieces during the landscape reconstruction of Xingye Avenue.It started from the practical terms to make people more understand the profound meaning of sponge city in-depth.A simulation analysis was conducted through SWMM software for actual data,including surface runoff,peak flow,and infiltration situation.It shows that the transformed Xingye Avenue is more in line with the sponge city design and development concept than before.
