Taking 17 park green spaces in Taijiang District,Fuzhou City,as the research object,based on the spatial syntax theory,using Dpthmap and Arcgis software to establish the line segment model,from the four dimensions of global accessibility,local accessibility,per-ceptual accessibility,and the ratio of global depth to connectivity,the accessibility of park green spaces in Taizhou District is comprehen-sively evaluated,and the optimization strategy is proposed.The results show that the global accessibility and local accessibility of parks and green spaces in Taijiang District are good,but there is a phenomenon of large individual differences in the accessibility of parks and green spaces.Perceived accessibility is generally high,but there are some park green spaces that are not attractive enough to residents,making their ratio of global accessibility to connectivity lower than the mean value.The ratio of global depth to connectivity of some parks is low,indicating that the scale and spatial quality of park green spaces need to be improved.In this regard,corresponding countermeasures are proposed in terms of improving the roads around the parks,appropriately increasing the parks and improving the quality of the parks in or-der to provide some insights for the optimization of the layout of urban green spaces.
