摘要
确定地震发生后人口位置及人口流动趋势,以2016年5月22日辽宁省朝阳市朝阳县4.6级地震烈度圈为数据提取范围,共采集了57890条位置信息。对采集的点数据分类,对不同时段和不同地点人口数据变化加以分析,同时绘制了人口流动图和应急疏散路线图,使得采集的位置数据可视化,为震后人口数据的获取提供有效途径,为震后灾情评估和应急服务提供技术支撑。
In order to determine the population location and population movement trend after the earthquake with magnitude 4.6 occurred on May 22nd,2016 in Chaoyang County,Chaoyang City,Liaoning Province,57890 mobile location information in the intensity radius was extracted,collected and sorted.Population data changes according to different times and different locations were analyzed,and the population track map and emergency evacuation route map were drawn in order to visualize the collected location data.The study may provide an effective way to obtain the population data after the earthquake and provides technical support for the post-earthquake disaster assessment and emergency services.
