| Urban green center is a green space located in the center of a city or a number of urban agglomerations.It has strong ecological conservation and social public service functions,and is an important part of urban green space system.With the further promotion of ecological civilization construction,the greening construction is in full swing all over the country.The concept of urban development in China has evolved from the original "Shan-shui City" and "Garden City" to today’s "Park City".In this context,the importance of urban green heart for urban development is self-evident.But at the same time,because of its large planning area,long development cycle,complex internal contradictions and other issues,green heart gives great challenges to planning and design.Therefore,from the perspective of landscape urbanism theory,exploring the design method of urban green heart in the new era has become the theme of this paper.This study first discusses the related concepts of Urban green heart and landscape urbanism theory,and focuses on the concept,type,composition,characteristics and existing planning and design problems of urban green heart.Based on the analysis of the research direction of landscape urbanism theory,the paper concludes five principles for the future development of urban green heart,which are ecological,dynamic,integrated,complex and cultural.In the fourth chapter,it puts forward five design strategies for the construction of urban green heart,constructs a progressive,self-sustaining and resilient development mode,reorganizes and organizes the site elements by using landscape,so as to realize the functions of ecological restoration,regional context inheritance,urban space integration and self-development maintenance.In addition,this paper also makes a detailed study and analysis of five practical cases,including Beijing Tongzhou Green Heart Park,Shaoxing Jinghu National Wetland Park,Shenzhen Qianhai New Town,Suzhou Shishan Park and Ningbo Ecological Corridor,and summarizes the success of their design.Finally,taking the design of Xishanyang Green Center in Huzhou as an example,this paper carries out the practical design application of the above research,advocates the construction of a new urban green center with "self-sustaining operation and promoting urban development",and provides new ideas for the planning and design of other urban green centers. |
