上海公园空间可达性与公平性分析

公园是城市绿色基础设施的重要组成部分,是城市居民游憩活动的重要场所,具有重要的生态、娱乐、休憩和社会文化等功能.在遥感和地理信息系统技术的支持下,以上海市为例,运用最小邻近距离分析方法时研究区公园的空间可达性进行了定量评价,并结合上海市第五次人口普查数据资料,采用需求指数,分析了研究区各街道居民对城市公园的需求情况,在此基础上,采用定序变量相关分析和因子空间叠置分析两种方法定量测度了研究区公园布局的空间公平性程度.研究结果表明:(1)研究区可达性水平总体上较高,超过半数的居住区出行不足1000 m即可到达一个公园,超过70%的街道可达性水平较好;(2)在街道水平上研究区公园空间布局总体上比较公平、较为合理,可这性水平与需求指数呈显著相关,很高或高需求的街道70%左右均具有很好或好的可达性.

Spatial Accessibility and Equity of Parks in Shanghai

Park is the main part of urban green infrastructure, the important recreation site for residents, and can provide ecology, recreation and social culture function. With the support of Remote Sensing and Geographic Information System, the accessibility of park in Shanghai was analyzed using minimum distance method. The needs index of each block group for park was calculated, based on the fifth census data, and than the spatial equity pattern was measured quantitatively, using rank correlation and spatial over...
