Study On Landscape Planning And Design Of Residential Area In Sponge City

The rapid urbanization process in China has changed the underlying surface of the city while changing the living conditions of the people.It brings a series of ecological problems to the city.The shortage of traditional rain and flood management in China and the current situation of flood and flood disasters in cities,under this situation,The country has carried out the construction of the sponge City.The residential area is the microcosmic site in the construction of the sponge.It is an important part of the construction of sponges.It is not only the important carrier and the main means of the construction of the sponge City,but also the most closely related site to the living environment.This paper analyzes the theoretical research and practical results of urban low impact development measures in European and American developed countries,such as LID,SUDS,WSUD and so on.Further analysis of China's sponge city facilities system.Study on the theoretical course of the management of rain and flood in China and the practical application of the construction of the sponge city in the residential area,characteristics of rain and flood resources and characteristics of population activities in residential areas.To combine the construction of the sponge with the landscape planning and design of the residential area.Analysis of the structure and function of the spongy residential area with five cases of domestic and foreign spongy residential areas.Study on the form of sponge landscape design using the conditions of different residential areas,Analysis of individual suitable sponge facilities construction practices,residential use of the runoff control ability and runoff decontamination ability.Analysis of the beauty of different landscape types in spongy city by using the SBE beauty evaluation method.Analysis of the significance of landscape elements by SPSS stepwise regression analysis.Comprehensive comparison of the effect of rainwater runoff control and landscape effect combined with the sponge facilities.Explain the natural conditions of Changde and its construction as the first pilot city of the sponge City.For the residential construction research of different types of sponge sponge residential area construction of 30 demonstration area,analysis of the main problems in the construction.Summarize the overall strategy transformation of Changde city residential and residential areas of different types of sponge city construction mode.Green rate greater than 30%to be built in residential landscape dominated by sponge.The types of residential areas with other consumptive site runoff rain function,the formation of internal allocation and balance index.Residential areas with green space less than 30%greater than 10%need to make use of limited green space for the rational distribution of sponges.The types of residential areas with the basic runoff plots within the consumptive itself.Green rate is less than 10%of the residential area should not completely in the case of runoff consumptive own excess runoff discharge into account.At the same time,it is discussed that combined with the local environmental characteristics to meet the needs of runoff and the need for decontamination,it is also necessary to consider the human historical factors to reflect their urban characteristics.Finally,selected the Changde Municipal People's Congress Standing Committee compound residential renovation project of sponge sponge practice.According to the climatic conditions of Changde City,the local residential sponge city construction of landscape planning and design of the general idea,design methods,design details are explored.
