Research On Localization Strategy Of Lianhuashan Sponge City Construction Based On WSUD Concept

With the deepening of urbanization in China,a large number of new urban areas are emerging constantly.The development of new areas requires more land for urban constr uction,so it will inevitably destroy the original ecological base and ecological environment of city to some extent.One of the best ways to solve this problem is the songe city constru ction,so as to achieve ecological construction and sustainable development in the new are a.Sponge City construction of China is still at an exploratory stage,especially for the few practice and research of the new urban area,and Sponge City constructions in the norther n mountainous region is less and less.This article takes the Changchun Lianhua Mountain Eco-tourism Resort as the research object,and carries on the related exploration of the sponge city construction,and provides the certain reference for the lotus city and similar area's sponge city construction.First of all,by analyzing the theoretical basis and research progress of sponge city construction at home and abroad,this article summarizes the inspiration from the construction of foreign sponge cities and the inadequacies of domestic construction.Through horizontal and vertical comparative study,it summarizes the advantages and ideas of sponge city construction based on the WSUD and provides the theoretical basis for the following research.Secondly,the paper carried out a comprehensive and detailed analysis of the basic elements and the necessity for construction of the sponge mountain city of Lianhua Mountain,it also summarized the basic elements such as its location,topography,climate,and water resources,and adopted land use research and water ecosystem research,the study of forest and cultivatedland ecosystems analyzed the necessity of Lianhua Mountain for sponge city construction.Then,from three aspects,the paper studies the localization of the construction of sponge mountain in Lianhua Mountain.First,the factors influencing the construction of mountain sponge city and the key points of construction;second,the factors influencing the construction of northern sponge city and the key points of construction;third,the influence of the new urban area on the construction of sponge city and the construction key points.On this basis,the article puts forward the goals,principles,core contents,and theoretical framework of Sponge City Construction in the Northern Mountainous New Area based on the WSUD concept.Finally,the article proposes the localization strategy of the construction of the sponge mountain city of Lianhua Mountain from three aspects: the construction of a macroscopic sponge system,the division of sponge function in the mid-scale,and the construction of a micro-site low-impact development facility.Taking the recent construction scope of Quanyan Town,a key area for the construction of the sponge city as an example,the article studies the layout and benefit evaluation of low-impact development facilities.
