手机定位人口数据在应急救援中的应用

随着智能手机的普及,基于手机定位的人口数据在突发性灾害应急救援领域发挥着日益重要的作用。以近几年地震灾区为主要研究对象,选择灾区中有代表性的旅游景区、县城及乡镇,获取这些区域手机定位的人口数据,同时采用传统方法估算区域内人口数量,并进行差异性对比。研究结果表明:差异性最大的是旅游景区、其次是县城和乡镇;在人口年度变化上,旅游景区的人口在7、8月份达到高峰,乡镇人口高值区出现在2月份,县城人口年度差异无明显规律。

Demographic Data based on Mobile-phone Location Applied in Emergency Rescue

With the popularity of smart phones,the pedestrian data based on mobile location plays an important role in the field of emergency rescue for sudden disasters increasingly.In this paper,the earthquake-stricken areas of recent years are taken as the main research areas,which are tourist attractions,counties and towns in the disaster areas.Based on mobile phone location and the traditional method we estimated the population of those areas,and then compared and analyzedthe differences.The results show that the biggest difference is tourist attractions,followed by counties and towns;in terms of annual differences,the largestpopulation in tourist attractions appeared in July and August,and the high-value at the township level appear in February,while there is no obvious regularity in the annual change of population in counties.
