基于公共交通的贵阳市公园绿地可达性分析

Analysis of accessibility of urban parks by public transportation in Guiyang

探讨公共交通方式下的城市公园绿地可达性对于建设生态文明城市有重要的意义。本研究基于城市公共交通综合评价贵阳市公园绿地的可达性。研究结果表明:1)步行与常规公交可达性均由城区核心位置呈不规则环状向外围逐渐变差;2)公园绿地步行可达性较好,87.43%的居住小区与82.63%的城市居民覆盖在30 min范围内;3)常规公交平均可达性较好且差异较大;4)步行与常规公交均可达区域分布于城区中心位置,市民出行方式选择多样化,综合可达性好;步行与常规公交均难可达区域分布于城区边缘区域,市民出行方式选择单一,综合可达性差。在上述分析结果的基础上,探讨贵阳市公共交通与公园绿地布局存在的问题及原因,并提出优化建议。

It is of great significance to explore the accessibility of urban parks by public transportation for the construction of ecological and civilized cities.In this study we evaluated the accessibility of urban parks by public transportation in Guiyang.The results showed that:1)the accessibility of urban parks by walking and common public transportation gradually decreased from the downtown area to the city periphery;2)the accessibility of urban parks by walking was good,within 30 min walking to 87.43%residential quarters and 82.63%residents;3)the accessibility by common public transportation was good,yet the difference was large;4)parks with good accessibility by walking and common public transportation mainly distributed in the downtown area,the choices of traveling methods were diversified,and the comprehensive accessibility was good;parks with poor accessibility by walking and common public transportation mainly distributed in the city periphery,the choices of traveling method were few,and the comprehensive accessibility was poor.Based on the results above,we discussed the problems and their causes of the public transportation and urban park layout in Guiyang,and put forward optimization suggestions.
