基于行为时空特征的老年人日常生活圈形态测度方法——以苏州古城为例

A Method for Measuring the Morphology of Daily Life Circle of the Elderly Based on Behavioral Spatial-temporal Characteristics:Taking the Suzhou Ancient City as an Example

社区生活圈是老年人日常活动的基本单元,如何精准识别老年人生活圈形态成为生活圈规划的核心问题。老年人日常生活圈本质上表征老年人与社区空间的供需关系。因此,本文通过PPGIS调查方法,归纳总结社区老年人的行为时空特征;根据老年人的行为时空特征数据,采用栅格法划分生活圈空间范围,在栅格中构建“频率-距离”统计模型识别老年人日常生活圈的圈层形态。通过对比三个苏州市典型社区的老年人日常生活圈形态,研究结果表明该方法可以测度不同社区老年人日常生活圈形态。

The community living circle is the basic unit of daily activities for the elderly,and how to accurately identify the form of the elderly living circle has become the core issue of living circle planning.The daily living circle of the elderly essentially characterizes the relationship between the elderly and the community space in terms of supply and demand.Therefore,this study summarizes the spatial and temporal characteristics of elderly people’s behaviors in the community through PPGIS survey method;based on the spatial and temporal characteristics of elderly people’s behaviors,a raster method is used to divide the spatial scope of living circles,and a“frequency-distance”statistical model is constructed in the raster to identify the circle patterns of elderly people’s daily living circles.The results of the study show that this method can measure the daily living circles of the elderly in different communities.
