Optimization Of Public Open Space Layout In Harbin New Area Based On Spatial Network Analysis

With the development of social economy,the rapid development of industrialization in all parts of the world has accelerated the process of urbanization.The rapid development of urbanization has accelerated the expansion of economy,population and land use.A series of problems have emerged in cities,including: less green space and relatively poor living environment;Excessive urbanization leads to traffic congestion,which leads to poor living conditions.The construction of new urban areas has become an inevitable choice for the development of modern cities.Public open space is mainly responsible for urban residents’ outdoor activities,communication and recreation,and is also the main place for urban residents’ daily activities.In the planning of urban public open space,it plays a very important role in improving the quality of life of citizens.In the construction and development of a new district,the planning and construction of urban public open space layout is an important aspect of a city’s development vitality.Based on the investigation in Harbin district public open space distribution characteristics,combined with GIS and spatial network analysis research methods,construction of Harbin new city public open space space network analysis model,from several aspects of Harbin new district to study the distribution pattern of public open space,and use the space network theory to optimize the existing problems.The core content of this paper is mainly divided into three parts:First of all,to summarize domestic and foreign research for public open space,the overall planning of new district of Harbin north district public open space classification screening,according to the site investigation and data collection,the distribution of the new district in Harbin,to open public space layout in the study area and spatial pattern analysis of the system.Secondly,according to the image of Harbin New Area,the public open space in Songbei District of Harbin New Area is vectorized,and the spatial network model is constructed.According to the space syntax theory,the spatial structure of the study area is analyzed from three aspects,namely,the degree of travel,the degree of integration and the spatial composition efficiency.Verifying the correlation between the three spatial indexes of travel degree,integration degree and spatial composition efficiency and the distribution of public open space.Finally,all kinds of research results are connected,and the distribution map of public open space in Songbei District of Harbin New Area is superimposed with the spatial network model map,so as to discuss each type of public open space,and then explore how to choose the location of each type of public open space in urban space.To improve the layout of public open space in Songbei District of Harbin New Area,and then optimize and implement the layout of public open space in Songbei District of Harbin New Area from multiple aspects.
