Design Of Riverside Green Space At Dasi River In Jiyang District, Jinan City Based On The Concept Of Low-impact Development

Cities are the space on which human beings depend,and the crystallization of human wisdom for thousands of years.However,with the continuous advancement of urbanization in China,the ecological problems of cities have become increasingly prominent,especially the urban water environment.In recent years,the research on urban river courses has been a major theme in the landscape architecture discipline,and the main focus is on the restoration of river ecology.Among them,the low-impact development concept is the most important and the most extensive.In 2012,China proposed the sponge city theory,and low-impact development measures became the main implementation direction.Through the study of ecosystems,it considered the development of the city and the circulation of nature as a whole,and promoted the mutual symbiosis between city and nature,which became the solution to the urban water environment.The main means of the problem.Countries and provinces and cities have successively issued relevant legal documents and carried out extensive practical activities,but the degree of rationalization of the combination of theory and practice is not yet ideal.This article discusses the advantages and specific implementation methods of using lowimpact development theory to guide design in urban riverside green space through the analysis of domestic and foreign relevant excellent case strategies and research on low-impact development theory,and combines with relevant laws and regulations to construct Rationalized landscape construction strategies and processes,taking the design of the Dasi Riverside Greenbelt in Jiyang District,Jinan City as an example to carry out landscape practice under the low-impact development concept,and build a multi-dimensional integration of ecological environmental value,humanistic value,social value,economic value,etc.River landscape zone,and through SWMM model calculation to verify the rationality of the design method,to further explore the scientific guidance of low-impact development concept on practice,and also provide a case reference for future urban riverside green space design practice.
