Research On Landscape Planning And Desgin Of Zhuanghe Jiangjun Lake Area Based On Stormwater Managemant

In recent years,with the development of industrialization and urbanization in China,many cities in China suffer from the shortage of water supply,floods an d water quality deterioration.The traditional “gray” infrastructure only attaches importance to the rapid drainage,ignoring the protection of the natural hydrological characteristics,and can not meet the needs of the contemporary urban development and construction.At the beginning of 2013,with the idea of "sponge City" in the Central Urbanization Conference,the idea of natural accumulation,natural infiltration and natural purification has become an indispensable part of urban construction.2016,Dalian Zhuanghe was approved to become the second batch of national sponge city construction pilot city,and Zhuanghe Jiangjun Lake area as the background of the landscape resources are richer and the urban areas are diverse,is a good model for the construction of “Sponge City” area.Under this background,this paper,from the perspective of stormwater management,discusses the landscape planning and design countermeasures to meet the function of waterstorm,and under the precondition of improving the urban water environment and meeting the objectives of the management and control of waterstorm,to create a good landscape and improve the quality of the environment.This paper analyzes the basic theories of stormwater management,which have the functions of rainwater retention,infiltration,purification,utilization and storage,is constructed from the source control,midway transmission and terminal control three rainwater runoff control system,and then summarizes the landscape elements and the planning and design methods of stormwater function.And through the research of the relevant excellent cases of the stormwater management,the author summarizes the design idea and provides the sufficient theoretical support for the subsequent design practice.At the same time,based on the natural conditions of urban location,environment and hydrological characteristics of Zhuanghe,combined with the present municipal drainage system and its drainage capacity,the paper puts forward that landscape planning and design is the necessary means to solve the water environment problem of Zhuanghe.Through the field investigation,detailed analysis of the Zhuanghe Jiangjun Lake area residential district landscape,urban road landscape,urban green space landscape,urban water landscape four aspects of the status of stormwater function,and summed up its current situation of stormwater,that is: The pattern of stormwater management is imperfect,landscape lack of stormwater function and water pollution.In the end,this paper puts forward the countermeasures of landscape planning and design based on stormwater management: it puts forward to construct perfect greenbelt landscape system,unobstructed rainwater drainage system and the whole planning countermeasure of stormwater pattern in three levels.;it puts forward the landscape of the residential district landscape,the city road landscape,the city green landscape,and the water landscape which are The construction methods of stormwater function in four aspects;and the paper puts forward the measures of improving water quality in two directions of traditional management means and stormwater administration.Through the above three countermeasures,this paper aims to create a good urban landscape,strengthen the function embodiment o f the landscape,expand the existing management means of stormwater,and provide some guiding significance for the sponge city construction of Zhuanghe.
