With urban reformation and opening becoming deeper, the work of protection against earthquake and disaster reduction would
be more important. In this paper, some ideas are suggested about establishing the information system for emergency decisions
on protection against earthquake and disaster reduction in cities. The information system mainly includes a subsystem for
rapid evaluation of damage loss from earthquake (which includes input of seismic information, distribution of earthquake intensity,
evaluation of seismic fragility on all social factors and etc.) and a subsystem for the decisive information of seismic emergency (which mainly includes project of disaster relief, project
of personnel evacuation, dangerous degree warning for the dangerous articles-storing places and protection measures against
them, assistant decision on fire due to earthquake, location of head-quarter for providing disaster relief, and etc.). It is thought that the data investigation and collection about all kinds of buildings (including lifeline engineering)
are the most important and difficult work as establishing this system. 相似文献

After an earthquake, earthquake emergency response and rescue are important ways to mitigate earthquake-induced losses. Various earthquake emergency maps can provide effective references and guidance to those actions. Currently, related studies include the investigation on symbols of emergency maps, remote sensing emergency mapping and GIS-based mapping methods. However, the existing studies overlook the characteristics of rapidity, dynamicity and variety of presentation methods in making earthquake emergency maps. In this paper, a map template matching method is used to quickly make earthquake emergency maps considering their characteristics. We take investigations on the service objects(users)of the earthquake emergency maps to understand the needs of making earthquake emergency maps. The audience theory in mass media field and map information transmission theory are adopted to classify the users of the earthquake emergency maps into four categories: earthquake emergency commanders, technical staffs for decision-making, earthquake emergency rescuers, and the public. The components of different types of users are described and then their diverse demands in earthquake emergency maps are analyzed, such as the needs of on-field disaster information maps, earthquake information maps, physical geography and social economic maps. Following those needs, we introduce the representation methods of the earthquake emergency maps according to their formats(vector or raster)and contents, such as point symbolization method, kilometer grid method, line symbolization method and range method. Then, we study the rapid plotting method of earthquake emergency map based on map template matching method. The core steps of the method include: 1)before earthquake, the templates of different earthquake emergency maps are designed, prepared and connect the earthquake emergency features with their related spatial database. The map layout and map elements are stored in the templates. 2)After earthquake, the earthquake emergency features will be generated from seismic models(such as attenuation model of earthquake magnitude and seismic intensity)or the information obtained from field investigation. 3)Corresponding earthquake emergency map template is selected in accordance with the generated seismic features. And the features are used to update related features inside the selected template. 4)Minor adjustments are made such as to the map scale and some map annotations to finally generate the formal earthquake emergency map. Architecture of template system of the earthquake emergency maps is designed, including map user level, map template level, template layer level and map element level. Regrading to the architecture, the general map template of earthquake emergency is presented which includes four main regions: title region, main picture region, auxiliary region and annotation region. The main picture region is the essential, which lays geographic background maps and earthquake emergency features. Finally, an earthquake emergency mapping system is developed. Based on the system, a case study is presented, which demonstrates making a simulated seismic intensity influence map. From three aspects, the case presents the application of the template-matching method including: generating earthquake emergency features, substituting the features inside the template with the generated features, and revising map annotations. Therefore, the map template matching method is verified so that it can be used to quickly generate various earthquake emergency maps. 相似文献

地震应急现场信息分类初步研究 总被引：11，自引：2，他引：9
地震应急现场信息分类的核心目标是实现灾情信息的快速上报、关键信息特征的识别和为辅助决策提供客观现实依据。按照信息内容的本质属性,依据发生什么事件、产生什么影响、对产生的影响有何响应,针对响应有什么成效这样的思路将地震应急现场信息分为地震震情信息、灾情信息、应急处置信息、处置效益信息4个大类。在对信息字段进行定义时,考虑了信息来源,将信息本质属性与信息源进行有机结合。分类成果可以应用于地震行业应急处置和各级政府应急处置的信息汇集、分析、处理,还可以依据分类体系充分利用社会公众参与灾情速报。由于灾难事件的应急处置具有相似性,本研究的成果适当修改后也可应用于其它行业的应急处置工作。 相似文献
