Spatial Analysis And Optimization Of Disaster Prevention Park Based On Space Syntax

With the development of the city and the economic growth,the impact of earthquake disaster on most of the cities of our country is increasing,and the construction of disaster prevention and refuge places has become an important part of the city construction.Urban disaster prevention park is an important guarantee for disaster prevention and mitigation.The effect of its construction and transformation will directly affect disaster shelter and urban safety.On the basis of the existing green space function,the urban park as the basic spatial structure is transformed into a disaster prevention park,which is the main way for the current disaster prevention park construction.However,whether the construction or reformed disaster prevention park can play a role in disaster prevention and meet the needs of disaster prevention so as to provide security protection for the public at a given time is worth exploring.The spatial layout and spatial shape of disaster prevention parks in urban neighborhoods have an important impact on disaster prevention efficiency in their service areas.At the same time,the organization of different space within disaster prevention parks has played an important role in the effectiveness of disaster prevention space and the efficiency of disaster prevention.On the basis of existing research,this paper introduces spatial quantification analysis methods such as space syntax,Suzhou Disaster Prevention Park as the research object,and through dedicated analysis software such as Depthmap and GIS,to quantify disaster-prevention parks and surrounding areas on individual levels of city blocks and parks.Space,study the rationality of spatial layout of urban disaster prevention parks,explore the effectiveness of disaster prevention space within urban disaster prevention parks and the efficiency of disaster prevention,and propose optimization suggestions for space layout and internal space organization of disaster prevention parks.This study provides new perspectives and methods for the spatial layout of urban disaster prevention parks,and provides reference for the planning,design,and renovation of disaster prevention refuge parks.The main research content is as follows:(1)Literature review and related concepts are explained.The "urban disaster prevention park" is regarded as a complete research object.Through the reading and sorting of a large number of related research books and materials,the relevant theory research progress and practice at home and abroad are comprehensively described,and the construction and research status of disaster prevention parks are clarified.Explain thetheoretical basis of spatial analysis of urban disaster prevention parks,determine the main content of research and spatial quantification methods.(2)Study on the rationality of the layout of city blocks for disaster-prevention parks.Taking Gusu District Disaster Prevention Park in Suzhou as the research object,using space syntax to quantitatively analyze from the perspective of city blocks,combining with GIS spatial network analysis technology,from the service area,spatial organization within the service area,Gusu District spatial structure,disaster prevention capacity and prevention From the perspective of the development potential of disaster space,the location,traffic organization and development direction of the spatial layout of the disaster prevention park in Gusu are analyzed,and the existing problems and layout rules of disaster prevention parks are summarized.(3)Research on the effectiveness of space organization in disaster prevention parks.A spatial analysis of the space of six typical disaster-prevention parks in Suzhou Gusu District was conducted using the spatial syntax from the perspective of the park's internal space.The exhaustion axis model and view model in space syntax were used to analyze the degree of integration,connectivity,degree of penetration,and degree of synergy.And spatial quantification indicators such as population simulation,to study the effectiveness of spatial distribution of disaster prevention in parks,and to make horizontal analogy,summarize the spatial organization characteristics and disaster prevention effectiveness of different types of urban disaster prevention parks,analyze their advantages and disadvantages,and summarize law.(4)Discussion on space optimization strategy of disaster prevention park in Gusu District.Based on the content of the previous analysis,from the perspective of the spatial layout of disaster-prevention parks,the current issues have been addressed by the principles of optimization,accessibility,system coordination,new disaster-prevention parks and corridors,adjustment of local urban spatial organization,and acceleration of service parks.Expanding the solution;From the internal space organization level of disaster prevention parks,in order to solve the current problems,the optimization principles of effectiveness prioritization,general disaster reuse,and intensive transformation,as well as the promotion of overall planning functions,optimization of topology,and adjustment of forms were proposed for disaster prevention parks.Construction and renovation provide certain theoretical and methodological guidance.
