利用多源数据识别宁乡产业园区空间范围

Spatial Range Identification of Ningxiang Industrial Park Based on Multi-source Data

从交通等时圈、城市联系圈、城市势力圈3个维度出发,基于百度时空数据、手机信令数据、社会经济人口统计等多源数据,采用多维定量计算分析方法,首先以乡镇为单元确定研究范围,分析周边潜在的空间竞争引力节点;然后采用交通等时圈法划定各引力节点的空间可达性范围,城市联系圈法分析各引力节点的城市联系强度,城市势力圈法分析各引力节点的城市势力范围;最后综合分析三者得到宁乡产业园区空间综合引力范围,根据行政区边界、地方政府发展意愿等修正原则得出修正后的空间引力范围。

Starting from the three dimensions of traffic isochronous circle,urban connection circle and urban power circle,based on multi-source data such as Baidu spatio-temporal data,mobile phone signaling data and social economic and demographic statistics,using multi-dimensional quantitative calculation and analysis method,we took township as the unit to determine the research range,and analyzed the potential gravitational nodes of surrounding spatial competition at first.Then,we used the traffic isochronous circle method to delimit the spatial accessibility range of each gravitational node,used the urban connection circle method to analyze the urban connection intensity of each gravitational node,and used the urban power circle method to analyze the urban power of each gravitational node.Finally,through comprehensive analysis of the three factors,we obtained the comprehensive spatial gravity range of Ningxiang industrial park,and the revised spatial gravitational range based on principles such as administrative boundaries and local government development intentions.
