基于GIS的初评估方法在盈江5.8级及缅甸7.2级地震后的应用

摘要

在“3·10”盈江5.8级及“3·24”缅甸7.2级地震发生后,对比基于GIS的地震灾害损失初评估方法,在震后1小时内给出的云南灾区范围、灾区人口、灾害直接经济损失、人员伤亡、失去住所人数的初评估结果与地震现场评估结果,来验证该方法的可行性和实用性.通过对比分析,找出基于GIS的初评估方法存在的问题,并期望通过实际地震的检验,不断发现问题,并改进、完善该方法,使之能更好为震后的科学决策和快速应急响应服务.%We apply the primary assessment method based on GIS for the Yingjiang MS5. 8 earthquake on Mar. 10, 2011 and the Myanmar Ms7. 2 earthquake on Mar. 24, 2011 to verify its feasibility and practicality through comparing the primary assessment and the field assessment on areas, population, direct economic losses, casualties, and number of homeless of disaster areas in one hour after earthquake. Through comparative analysis, we find problems of the primary assessment method, then modify and improve it through seismic testing, so that the method can better serve the scientific post-earthquake decision-making and rapid emergency response.
