【摘要】 通过分析当前震害评估工作的现状和存在的问题,提出了基于GIS技术构建数字等震线模型的基本原理和技术思路。通过建立云南数字等震线模型及其在2007年6月3日宁洱6.4级地震应急中的使用,检验和论证了该模型的可行性和实用性。分析了模型计算结果与实际灾评结果存在差异的原因,以确立该模型在今后地震应急工作中的研究和发展方向。更多还原

【Abstract】 Through analyzing the status quo and problems of current earthquake disaster evaluation work,we proposed the basic principle and technical idea of Digital Isoseismal Model based on GIS,and established the model. We applied it to the Ning’er MS6.4 earthquake emergency,found the model was feasible and practical.But the results from the model slightly differs from those from the field investigation. We analyzed the cause of discrepancy in order to find the direction of research and development for the model in earthquake emergency response in future.更多还原
