| The first group is the disaster of the earthquake, with a sudden, devastating moment features a serious threat to human life and property safety. China is one of the world’s most earthquake-hit countries, at present, China has32.5%of the country, nearly50%of urban and67%of the metropolitan area is located in the degree of intensity Ⅶ. And studies have shown that the likelihood of the occurrence of the next50years of the devastating earthquake of great large. Now, China has formed an earthquake monitoring and prediction, earthquake disaster prevention and emergency rescue three major earthquake disaster reduction system. However, the earthquake prediction is still unresolved problems of the world. Under the existing technology and economic conditions, Construction of the earthquake emergency rescue system because of less investment, quick results, more realistic get more and more attention.Earthquake emergency plan as a possible response to the earthquake disaster, ensure reasonable, quickly and efficiently carry out emergency relief activities, to reduce casualties and property losses and pre-established rescue plans or programs, play an important role in the earthquake emergency rescue work. Scientific and effective emergency plan can not only increase the resilience to disasters, but also improve the efficiency of the rescue after the disaster. However, the current major earthquake emergency plan to store the text as a way, in a real earthquake emergency rescue process exposed a lot of problems, for example the content of expression is not intuitive, query and operability is not strong, the lower efficiency of extracting useful information, can’t automatically associated dynamically according to the earthquake developments targeted content disposition and so on. These problems lead directly to decision-makers difficult to make scientific decisions and affecting the effective implementation of the earthquake emergency rescue.With the development of computer science and technology, an effective way to solve these problems is to use such as the computer technology, network technology, geographic information systems theory and methods into the execution of an earthquake emergency plan, make the earthquake emergency plan digitized. In recent years, though digital technology has been successfully applied to a number of areas of disaster and accident rescue emergency plan implementation process, further research needs to be applied in the field of earthquake emergency rescue. Based on the formal description, digital modeling (XML), systems integration and geographic information systems research contingency plans to achieve digitization of key technologies, earthquake emergency plan around the design, development and implementation of executive support system, the main work is as follows:(1) According to analyze the content and structure of a typical earthquake emergency plan, apply the ontology-based knowledge representation and put forward earthquake emergency plan formal methods. Change the use of natural language text in the form of an earthquake emergency plan into the computer can understand and deal with the structure and logic of the form.(2) Make the current static storage format earthquake emergency plan into a digital storage format of contingency plans, to complete earthquake emergency plan digitized program designed to store and retrieve the relational database model is based.(3) Based on the earthquake emergency plans to formally describe and digital modeling, in ArcGIS platform, using ArcGIS Engine and Microsoft C#. NET development approach combining, earthquake emergency response as center to build earthquake emergency plan for the implementation of the auxiliary systems, develop the contingency plans into a series of operating procedures and the order can be executed with the earthquake emergency events evolution, to achieve the intelligent execution of earthquake emergency plan.Finally, summarize the results and make prospects for further problems and research directions. |
