摘　　要：城市公共绿地的分布及可达性与宜居品质紧密相关,研究选取上海市黄浦区和伦敦一区为研究对象,基于互联网开源大数据和ArcGIS平台,选取绿地、面积、人口等基础要素,利用引力模型下的两步移动法,建构上海黄浦区和伦敦一区绿地资源分布的定量研究与对比,分析得出上海黄浦区的绿地空间的供给总量、分布平衡度和可达性均远低于伦敦一区,其中绿地资源总量和人口密度空间分布不匹配是核心问题。The distribution and accessibility of urban public green space are closely related to the quality of livability. The paper selected Shanghai Huangpu District and London District 1 as the research objects. Based on Internet open source big data and ArcGIS platform, the paper selected basic elements, such as green space,area, and population, and then conducted quantitative study and comparison on the distribution of green space resources in Huangpu District in Shanghai and in District 1 in London through the two-step movement method under the gravity model. The analysis showed that the total supply, distribution balance and accessibility of green space in Shanghai Huangpu District were far lower than that in District 1 of London, and the mismatch between the total amount of green space resources and the spatial distribution of population density was the core problem.
