基于人口公里格网的地震压埋人员分布评估方法的应用与评价——以甘肃岷县漳县6.6级地震为例

Application and Evaluation on a Evaluating Method for Distribution of Earthquake Buried Personnel Based on Population Kilometer Grid: Taking Minxian-Zhangxian M6.6 Earthquake as an Example

采用基于人口公里格网的地震压埋人员分布评估方法,结合甘肃省人口公里格网数据,以ArcGis软件为平台,对2013年甘肃岷县漳县6.6级地震进行了压埋人员的分布评估,并结合甘肃地区的人口分布区域特点及岷县漳县6.6级地震的实际特点,对该方法中的参数进行本地化改进,并将评估结果与实际分布进行比较分析。结果表明:改进后的方法使评估结果的适用性有了一定程度的提高,可在震后快速给出震区人员压埋分布评估结果图,实现对甘肃地区震后地震压埋人员评估辅助决策内容的有效补充。

Based on population kilometer grid data,we evaluated the distribution of the buried people of the 2013 Minxian-Zhangxian M6.6 earthquake by a method of evaluating the distribution of buried personnel in earthquake based on population kilometer grid. Combining the population distribution in Gansu province and the characteristics of Minxian-Zhangxian M6.6 earthquake,we improved the parameters of this method for some localization optimizations,and compared the evaluation results with the actual distribution. The evaluation results show that the improved method improves the applicability of the evaluation results to a certain extent. It can quickly give the evaluation result map of the buried personnel distribution in the earthquake-striken area after the earthquake,and realize the effective supplement of the assistant decision-making content for the evaluation of the personnel buried in Gansu area after the earthquake.
