\May 12, 2008, the devastating earthquake in Wenchuan County, Sichuan Province, China's 8.0 Richter King, shock pain nerves of every Chinese person it brought great loss to our country, but also the whole of China twisted into a rope, and write the earthquake relief period epic chapter of history in the face of disaster. The coming period, the more severe and complicated situation of natural disasters, the earthquake is still one of the risks of major natural disasters facing our country. Mitigate earthquake risk, and improve China's urban earthquake disaster management the ability to become very real and quite challenging problem. Well before the earthquake prevention and preparedness work is to improve the level of risk management, an important factor to ensure that the post-earthquake emergency work effectiveness. May 11, 2009, the State Council Information Office published a White Paper on \further requirements. ArcGIS Engine component development technology is currently the most popular of this study urban earthquake disaster risk management information system, the basic unit of information management community for earthquake damage risk assessment and earthquake situation, set data entry, analysis, management, query, expression as a whole, to achieve the integration of graphics, to meet the needs of urban earthquake. This article contains a total of seven chapters, the main work can be summarized as follows: (1) the relevant theoretical and technical review systematic exposition of the concept of urban earthquake disaster risk management methods, implementation steps; Summary component GIS development technology, its characteristics, structure, development platforms and languages, the and introduces ArcGIS Engine development process through a small example. (2) the design and establishment of urban earthquake disaster risk management information system (UEDRMIS) to the user's needs as the starting point, to determine the system that you want to achieve the overall goal, detailed elaborate a UEDRMIS the architecture design, system functions and to achieve and other aspects of the content, the completion of The overall design of the system. Able to realize the function of each module, the user interface module, the logical relationship between the modules, the key modules of data processing process technology and methods were described in detail. (3) design and establish UEDRMIS system database in this article the system databases logically divided into two parts, the underlying database and results database, and building a database from the database processes, data standards and data entry and stored a few aspects of the system database gave a general introduction, an exemplary description of some of the major categories of the data structure of the table. (4) to summarize the key technology in the development process combined with the specific projects of the development process, and summarizes several key technical problems in the development of ArcGIS Engine: interactive technology the query retrieval techniques, map symbols, with the main map and packaged installation techniques. The preparation of the sample code focus on normative readability. (5) through examples show the the systems face of Qingdao City project data, through an example, showing the effect of the overall operation of the system, the the oriented system further research and promote the application of demonstration. The innovation of this paper are: (1) existing similar systems are several functions distributed across several computers up to achieve this thesis, the first time, all functions are integrated into a computer, the earthquake disaster risk management information systems. Friendly system interface design, simple operation, and does not require special training, users will be able to skillfully use the system, so that users can rely on powerful tools. (2) using ArcGIS Engine component technology, earthquake disaster risk management information system, the development of breakthrough technology to make the system has a better price, you can use the system do not need to upgrade the existing hardware and software configurations, the The system is able to promote the open as one of the primary seismic work services attractive.
