A Study Of Urban Green Space Form Of Hexi In Nanjing

Under the background of rapid urbanization,higher requirements are placed on the planning and construction of urban green space.The urban green space form focuses on the overall spatial structure of urban green space and directly affects the ecological benefits of urban green space.In coordinating the relationship between urban space and natural space and promoting the orderly development of cities,the research on urban green space form has broad prospects.However,for a long time,urban green space and its spatial form have been passive and lagging behind in the process of urban development.Therefore,from the perspective of the overall form,this paper conducts multi-level and systematic analysis and evaluation of urban green space,and re-examines the results of urban green space planning and construction in the Hexi area to promote the integration of related theories and the improvement of practical work.Firstly,based on the research background and the basic theories and related research of urban green space morphology,this paper preliminarily sets up the research framework of this paper,then further summarizes the relevant research methods,and initially establishes the analysis framework of urban green space form from three aspects: composition,shape and pattern.Then,combined with the research of landscape metrics,this paper further refines the relevant analysis indicators,and thus roughly establishes an analysis and evaluation system of urban green space form.In recent years,the Hexi area of Nanjing has undergone a process of rapid development and expansion as a new city,and has undergone rapid development and expansion.The land use and the spatial pattern of Hexi have undergone tremendous changes.This paper summarizes its urban development and planning through basic data such as urban development process and superior planning of the Hexi region,and then combined with the field survey and investigation,using the methods of ArcGIS and FRAGSTATS,the current urban green space form is analyzed systematically,and further potential problems are analyzed based on specific spatial analysis.Finally,the spatial forms of urban green space in Hexi area are summarized on this basis.Based on the analysis and conclusions and reflections on current urban problems in the Hexi area,this paper proposes macro optimization guidelines for urban green space formation in Hexi,and proposes optimization strategies based on concrete space.Finally,according to the results of the research and the consideration of the current situation of urban green space planning and construction,this paper puts forward the suggestions of the urban development mode of ecological priority and urban green space form priority.
