摘　　要：运用科学手段对城市公园绿地的服务范围及其合理布局进行分析,有利于城市良好的生态环境、城市面貌与稳定秩序,并为居民提供高效与公平的日常游憩场所。文中以武汉市江汉区为例,基于GIS网络分析法,通过构建以道路网络、公园和人口为核心的矢量数据库,得到不同类型公园的不规则式服务范围与承载力。结果表明,20 min日常游憩服务范围占该区总面积75.5%,且菱角湖公园、王家墩公园、龙王庙公园的承载力较弱,由此得出江汉区存在真空盲区与隐形盲区。针对不同盲区,进行针对性的公园绿地优化布局,将居民日常休闲游憩与公园绿地空间布局切实地结合起来,实现公园绿地的合理布局。The science-based analysis of the service range and rational distribution of urban park green spaces is beneficial to the urban ecological environment,city appearance and stable order of living,and provides efficient recreational places for residents in a fair manner. The paper took Jianghan District of Wuhan as an example,and calculated the irregular service range and bearing capacity of different types of parks based on the GIS network analysis and vector databases of road networks,park and population. The results showed that the service ranges of daily recreation with 20 min limits account for 75. 5% of the total area,and the bearing capacity of Lingjiao Lake Park,Wangjiadun Park and Temple Park is relatively low. We concluded there exist empty blind areas and latent blind areas in Jianghan District. With an eye to different blind areas,we made some targeted optimal design of the park green spaces by effectively combining park green spaces and daily recreation of residents,which achieved reasonable layout of park green spaces.
