Research on the Accessibility of Urban Ecological Recreation Space based on Spatial Syntax:Taking Weihai as an Example
Based on the theory of spatial syntax,53 green spaces within the scope of Weihai City are taken as the research objects,CAD drawings of roads in Weihai City are drawn,and axis and line segment models are established.And the spatial calibration is carried out by POI data of Weihai City.Depthmap software was used to evaluate the travel accessibility and psychological accessibility of ecological recreation space in Weihai City,and put forward the layout strategy of ecological recreation space in Weihai City.The study shows that:(1)The overall travel accessibility of ecological recreation space in Weihai is high,while the psychological accessibility is low.(2)The ecological recreation space in Weihai has a high degree of overlap with the optimal range of accessibility,and the spatial layout is reasonable.(3)The ecological recreation space in Weihai has the phenomenon of uncoordinated regional development,so we can give full play to the advantageous conditions of each administrative region,and combine the hills,lakes and coastal scenery of two districts and two cities to achieve spatial complementarity.
