摘　　要：运用GIS软件,基于南京市主城区道路网络并结合街道人口分布,定量分析了研究区公园绿地的可达性和各街道居民出行的便捷性。结果表明:研究对象可达性整体上较好,大部分区域步行10min、非机动车5min或机动车5min可以到达最近的公园绿地;大部分街道便捷程度较高,步行15min、非机动车10min或机动车5min可以到达最近的公园绿地。将影响公园绿地可达性的因素归纳为4个方面:公园绿地本身的质量、道路网络的完善程度、所采取的交通方式和城市居民的分布状况。Using GIS software and combining with the distribution of street population,accessibility of garden green space and citizens＇ convenience of every street of the city proper of Nanjing are quantitatively analyzed.Results show that the whole accessibility of garden green space of Nanjing is good but bad in some zones.Most of the regions can be arrived within 15minutes on foot,10minutes by non-motorized vehicles and 5minutes by motorized vehicles.Fine-accessibility zones mainly distribute in Xuanwu,Gulou,Baxia and Qinhuai,while bad-accessibility zones mainly distribute at the edge of the city proper such as streets of Honghua,Guanghua and Shuangzha and so on.Results of convenience of residents of every street show that most of the streets are relative convenient that the nearest garden green space can be reached in 15minutes on foot,10minutes by non-motor vehicle or 5minutes by motor vehicle at the street level.Based on above analysis,four factors on the green space accessibility are summed up：quality of garden green space,condition of traffic network,means of transportation and distribution of citizens.
