基于宜出行数据的人口活动时空动态变化研究——以石家庄市鹿泉区为例

A Study on the Spatial and Temporal Dynamics of Population Activities Based on Easy go Data:Taking Luquan District of Shigiazhuang as an example

使用Python程序抓取研究区内人口分布热力值数据,通过ArcGIS软件中的核密度分析工具和空间分析方法,探究不同时段研究区所在地区及下辖乡镇人口活动分布时空特征。结果表明:人口活动在工作日呈现出“白天向心,夜间离心”的动态变化过程,休息日则与之相反;鹿泉区呈现出与主城同城化发展态势,具有较强就业吸引力,开发区及东部地区是域内主要就业活动空间;鹿泉区具有一定的休闲活动吸引力,但相对较弱,与主城区存在一定差距;根据热力值变化情况,区域内乡镇可分为休闲活力地区、休闲就业活力地区、就业活力地区和居住活力地区4种类型。

Using a Python program to capture thermal data of population distribution in the study area,the spatial analysis method and the kernel density analysis tool in ArcGIS software were used to explore the spatial and temporal characteristics of population activity distribution in the study area and the townships under its jurisdiction at different times.The results show that the population activities show a dynamic process of“centripetal during the day and centrifugal during the night”on weekdays,and the opposite on rest days.The Luquan district shows a development trend of co-location with the main city and has a strong employment attractiveness,with the development zone and the eastern part of the district being the main space for employment activities.The Luquan district has a certain leisure activity attractiveness,but relatively weak,and there is a certain gap with the main urban area.According to the change of heat value the townships in the region can be divided into four types,including leisure vitality areas,leisure employment vitality areas,employment vitality areas and residential vitality areas.
