Study On Landscape Design Of Rain Garden In Harbin

With the acceleration of urbanization,the proportion of gray infrastructure in urban construction is increasing,leading to serious pollution of urban rainstorm runoff,shortage of groundwater resources,urban floods and drought and other urban problems.In 2014,witih the introduction of the Technical Guide for Sponge City Construction by the Ministry of Housing and Urban-Rural Development,the degree of attention paid by researchers to the green infrastructure has gradually increased,bringing a new opportunity for urban rainstorm management.Rain garden is an important technical measure in the construction of a sponge city.Its main role is to control rainwater runoff,sedimentation and purification of rainwater,improve microclimate,beautify the environment and other ecological functions and landscape functions.In recent years,with the proposal of the construction of sponges,the attention of major cities in China to the construction of rain gardens has gradually increased,and researchers have increasingly studied the gardens of rainwater.This paper analyzes the influencing factors of landscape design and landscape elements of Harbin rain garden,and puts forward the construction method of Harbin rain garden landscape.Combining rain garden Landscape Design Theory with Harbin City’s First Sponge City Demonstration Project,Rain Garden Landscape in Qunli Health Ecological Park as the research object.Aiming at the existing landscape elements of the existing infiltrating rain garden and water-storage-type rain garden on the site,this paper analyzes and summarizes the landscape element,and proposes optimization design suggestions.Combining rain garden landscape design theory with practical projects.Through the rain garden landscape construction theory to improve the practice of Harbin rain garden landscape,so that Harbin rain garden theory and practice complement each other,improve the promotion and application of Harbin rain garden.This study has certain practical significance,with a view to providing reference and reference for the construction of the rain garden landscape system in Harbin City.
