Taking Zhengzhou Longhu Park as the research object,based on the spatial syntax theory,this paper used Depthmap software to make quantitative analysis of its spatial structure.The results shows that the overall integration of Longhu Park is 0.749 5,the local integration degree (topological radius is 3) is 1.469 2,the coordination degree is 0.350 957,and the intelligibility degree is 0.130 746. The analysis shows that the overall accessibility of Longhu Park is general, the intra-regional correlation is strong,but the inter-regional relationship is weak. The difference between dynamic space and static space is significant,the spatial attraction is unbalanced, and the local spatial recognition is low. Based on quantitative calculation and qualitative analysis,optimization strategies such as building an open space system integrating landscape and city, strengthening mobility between regions,building the spatial structure with rich levels, and creating the waterfront space with high comprehensibility are proposed.
