Design And Research Of Rainwater Garden In Shenyang Area

With the rapid development of cities,the acceleration of urbanization in Shenyang makes the area of gray infrastructure in the urban area larger and larger.In this way,the increase of stormwater runoff and serious pollution of groundwater resources lead to urban waterlogging and drought and other urban problems.In recent years,the proposal of sponge city construction provides a good policy and solution for urban rainwater problem.Rainwater garden is an important technical measure in sponge city construction,its main function is to control rainwater runoff,precipitation purification rainwater,improve microclimate,beautify the environment and other ecological and landscape functions.In recent years,with the development of sponge construction,more and more attention has been paid to the construction of rain gardens in major cities in China.However,China has a vast territory,and different regions have different climatic environment and rainfall characteristics,and the design form of rain garden is also different.In sponge city construction,rainwater garden has become an important means of urban construction due to its functions such as controlling rainwater runoff,settling and purifying rainwater,improving microclimate and beautifying environment.However,due to the vast territory of China,different regions have different climatic environment and rainfall characteristics,and the design forms of rainwater gardens are also different.The thesis summarizes the research on the construction,landscape and technical system design system of the rainwater garden at present,analyzes the climate characteristics and design environment of the rainwater garden in Shenyang,and analyzes the existing problems of the rainwater treatment in Shenyang based on the current situation and cases of the rainwater treatment in this region.Based on the technical system,the design system of Shenyang rainwater garden is constructed by explaining the technologies of water collection transmission,infiltration,filtration,purification and storage.Through experiments,the plant configuration of rainwater garden suitable for the sponge city construction in this region is preliminarily explored,and the design method of Shenyang rainwater garden is proposed.In Shenyang city rainwater garden sponge projects-Shenyang Jianzhu University ecological planting of the experimental base for the research object,the optimization design Suggestions,combining the rain garden landscape design theory and practice,through the rain garden design to build to guide the practice of the rainwater garden in Shenyang,Shenyang rain garden theory and practice of perfect complement each other,promote the popularization and application of the rainwater garden in Shenyang.
