基于GIS技术的厦门市地震应急管理系统

Earthquake emergency management system of Xiamen City based on GIS technology

为解决地震应急阶段的灾害损失评估、灾后救援人员和物资调配、救援路径分析等一系列重要问题,结合福建地区地震烈度衰减关系,通过GIS手段对厦门市不同震级、破裂方向等产生的地震烈度情况和影响范围以可视化形式展现出来。根据震区烈度分布模拟的结果,结合遥感影像目视解译,快速判断地震位置、范围和灾害损失情况及灾情可能发展的趋势。最后,结合最短救援路径分析和地震现场视频、360°全景环视场景等,决策者能够全方位、实时交互、身临其境般地感受现场灾情情况,及时调整救援力量的调度,提高决策的准确性和科学性。该系统也能为各级地震部门完善防震减灾信息系统提供一定的借鉴,促进防震减灾工作更加系统、合理地进行。

To solve the problem of the loss assessments in earthquake emergency stage,the allocation of post- disaster rescue workers and supplies,the analysis of rescue path and a series of important issues during earthquake emergency,combining with the attenuation relationship of earthquake intensity in Fujian Province,by means of GIS,the seismic intensity and influence scope under different earthquake magnitudes and rupture directions were displayed in a visual form. According to the simulation results of earthquake intensity distribution,combining with the visual interpretation of remote sensing image,we can quickly judge the earthquake location,scope and the disaster loss situation and the passible developing trend of the disaster. Finally,through analyzing the shortest rescue route and watching the video shot and 360 ° panoramic scene,etc. of earthquake scene,policymakers can really feel the disaster situation,and adjust the rescue force in time,which could improve the accuracy and scientificity of decision- making. The system can also provide certain reference for seismic departments at all levels to improve earthquake prevention and disaster reduction information system,and promote their work to be more systematic and reasonable.
