| 摘 要： | 从城市公共绿地空间结构和布局的角度入手，基于单要素引力模型和最小累计阻力，建立空间可达性与绿地规模质量和空间阻力间的关系模型，同时将空间阻力因素区分为步行阻力和人口密度。在考虑空间阻力的实际情况下，构建分布矩阵，优化提出城市公共绿地空间可达性的评价方法。并以武汉市汉口地区为例进行实证研究，利用GIS技术并通过网格划分，计算该区域内城市公共绿地的空间可达性分布；在此基础上结合汉口地区公共绿地分布的实际情况，给出其规划的建议性改进方案。

| Abstract: | In this paper, a method, assessment in urban public green space accessibility, is proposed through analyzing spatial structure and layout of urban public green space based on constructing model of relation between accessibility and green-space＇s quality and spatial resistance which was derived from single factor gravitation model and minimal cumulate resistance and which included resistance of walking and population density. Then the distribution of urban public green space accessibility was worked out by using GIS and dividing the study area into many regular grids based on the reality of spatial resistance. A case study in Hankou of Wuhan was implemented, and advice of improving the structural planning of Hankou＇s public green space was proposed which was based on the reality of Hankou＇s green space. |
