Research On The Layout Of Comprehensive Parks In Qingdao Based On The Spatial Syntactic Accessibility Evaluation

As an important “green window” of the city,urban parks play an important role in the urban green space system.At the same time,it is also an indispensable public urban recreational space for the urban residents,and plays an important role in the sustainable development of the city.With the rapid development of urbanizat ion and the goal of livable city construction,the great achievements have been made in the urban park construction.People's demands for quality of life and cultural spirit have been continuously improved.People also have higher requirements for the feeling of urban space.People not only pay attention to the quantity and qualities of city parks,but also pay more attention to the convenience of entering the park.The introduction of accessibility can well reflect the rationality of the spatial layout and the fairness of urban parks,and it is also an important index to measure the living standards of the city residents.However,most of the current methods for assessing accessibility of urban green space in China are mathematical calculations.The evaluation of accessibility of urban parks from the aspects of space and the residents' activities is relatively deficient.The spatial syntax theory can express the accessibility of the park through the research of urban spatial network from the perspective of topological network,and then get the orientation of Qingdao park layout optimization and renewal to make the layout structure more scientific and reasonable.For these reasons,this paper from the point of view of topological network,based on the comprehensive park in Qingdao as the research objects,using space syntax theory as a technical means,and with Depthmap as the main analysis tool,discusses the accessibility of park and puts forward the opinion of optimizing the park layout.The specific research process is: First of all,collating the information of the comprehensive urban parks and the city maps of Qingdao and conducting a survey on the use of the park.On this basis,extract the axial diagram of the urban road network.And using the space syntax theory and related research methods,through the analysis of the integration degree,intelligibility and urban efficiency value,research the accessibility of comprehensive urban parks in central Qingdao.Finally,based on the quantitative indexes obtained from the accessibility analysis,make a comprehensive evaluation of the accessibility of the parks and summarize the distribution characteristics of Qingdao city parks.This paper analyzes the problems existing in the park layout and the reasons leading to these problems,and takes the previous research as the theoretical support.Finally,it puts forward the scientific and reasonable optimization strategy for the park layout of Qingdao.
