| In the past decade,China has entered a period of high-quality development,and the process of urbanization has been significantly accelerated.Unfortunately,while enjoying the fruits of rapid development,many problems continue to emerge.As for how to better build a city and solve the urban problems,China puts forward the solution of performing the construction of ecological civilization and carrying out the pilot construction of ecological garden city.It is worth noting that Building urban green heart will become an important way to effectively solve urban problems,as it occupies an important position in the city and is an important ecological space within the city.The large-scale ecological space in the city contributes to the improvement of urban environmental quality,the improvement of urban climate and so on.However,the current function of urban green heart construction in China is relatively single,and the space is relatively closed.In this paper,the concept,origin,development,characteristics and functions of urban green heart in wetland type city are discussed theoretically by reading a large number of relevant literatures at home and abroad.,the classification of urban green heart is proposed for the first time from the perspective of internal ecological space types of urban green heart,and finally,combined with the related research on wetland landscape,the concept of wetland urban green heart park is put forward,and its characteristics and differences with other urban green heart and urban wetland park are introduced.Furthermore,based on the theories of landscape ecology,ecological restoration and recreation,the planning and design method of green heart in wet cities is explored.Moreover,its feasibility is substantially verified through the analysis and experience summary of the cases of Wuhan East Lake Green Heart,New York Central Park,Hangzhou West Lake,Wenzhou Ecological Park,Shaoxing Mirror Lake National Wetland Park,combined with the above theoretical achievements and many field investigations,taking Jinyang Lake Park in Taiyuan City as an example.In conclusion,Through research to find out a more targeted urban green heart planning and design method to enhance the ecological efficiency,strengthen the relationship between the city and the internal space of the green heart,contribute to the opening of the internal space and the promotion of the overall value of the green heart,and thus,achieving the high-quality development of China’s urban environment. |
