城市绿地是推进空间资源合理分配的重要基础设施之一.以广州市已建成的保障性住房为研究对象,采用GIS网络分析法,分析居住在保障性住房中的居民在不同交通方式下到达不同规模等级绿地的可达性.研究发现:①保障性住房人群到区级绿地和街道级绿地的可达性受交通方式影响较小.②通过核密度法和标准差椭圆法验证绿地与保障性住房的分布差异,结果表明保障性住房周边绿地覆盖范围小,各等级绿地的可达性较差.保障性住房的发展方向与绿地规划方向存在不一致,导致保障性住房处于绿地边缘位置.③地铁与公交或驾车的可达性高于地铁与步行的组合方式,主要因为绿地通常位于城市中心或繁忙地区较远的地方,且地铁与公交或驾车能覆盖更长的距离.本研究的结果对广州市在"十四五"规划中筹建新的保障性住房提供了有益参考,助力推动城市空间布局的优化.
Green space accessibility of affordable housing population in Guangzhou based on GIS network analysis method
Urban green spaces are one of the essential infrastructure elements for promoting the rational alloc-ation of spatial resources.Takingthe completed affordable housing in Guangzhou City as the researchobject,the study employs GIS network analysis to analyze the accessibility of residents living in affordable housing to green spaces of different scales and levels using various transportation modes.Research findings:1)The ac-cessibility of affordable housing residents to district-level and street-level green spaces is less influenced by transportation modes.2)The distribution differences between green spaces and affordable housing were veri-fied using kernel density analysis and standard deviation ellipse analysis.The results indicated that green spaces around affordable housing had limited coverage,and the accessibility to green spaces of various levels was relatively poor.The development direction of affordable housing did not align with the planning direction of green spaces,resulting in affordable housing being situated at the periphery of green areas.3)The accessibil-ity of green spaces is higher for the combination of subway and bus or car compared to the combination of sub-way and walking.This is mainly because green spaces are typically located farther from the city center or busy areas,and subway,bus,or car modes can cover longer distances.The results of this study provide valuable in-sights for Guangzhou City's efforts in building new affordable housing during the"14th Five-Year Plan"and can contribute to optimizing the urban spatial layout.
