Study On Spatial Decision Support System For Urban Planning On Earthquake Resistance And Hazardous Prevention

As the principal of urban disaster, earthquake is the emphasis of the studying on disaster prevention. With the development of technology and economic, the new technologies, new materials, new technology start to be used in the planning on earthquake disaster prevention. The spatial decision support system is an emerging field of science and technology. It is based on Geographic Information System, combined with the decision support system. The spatial decision support system is showed a strong advantage to be used in urban planning on earthquake resistance and hazardous prevention. Because it can provide the data, information and background materials that were required by policy-makers quickly and accurately, help decision-makers decide the objective of building model, modify the decision-making model, establish complex calculations of the space, provide various options, and evaluate and select project.This thesis was built a powerful, good versatile and reusability spatial decision support system for urban planning on earthquake resistance and hazardous prevention. The system is from the background of urban planning on earthquake resistance and hazardous prevention, taken the example of the city of ZhuCheng, ShanDong province, combined with the technology of GIS and relational database, and taken the technology of spatial decision support system as the core. The system also integrates several functions. It can provide decision support program and planning on earthquake resistance and hazardous prevention in the form of text and thematic map, such as land suitability evaluation, the building and foundation engineering, secondary disasters and disaster evacuation, and so on. The major contents of the dissertation are as follows:(1) Detailed planning and construction the overall functional structure and system integration, technology architecture of spatial decision support system for urban planning on earthquake resistance and hazardous prevention based theoretical framework of the spatial decision support system; (2) Construction of the database and its management subsystem, model base and its management subsystem, knowledge base and its management system, and the application of system functions layer based on system framework. (3) Proposed rectification plan and assistant decision planning on earthquake resistance and hazardous prevention for Zhucheng in the use of this system. Made optimization program in urban planning from the view of earthquake resistance and hazardous prevention, such as land use, construction zone, infrastructure (contains transport, water supply, power supply, hospitals, fire, communications, gas system), earthquake disaster prevention plans and measures, earthquake evacuation measures, construction plan for disaster prevention base, and so on. (4) Summed up the whole issue of study, and raised the direction for further work combined with the current trend of spatial decision support system.The innovative achievement of this thesis lies in introducing spatial decision support technology into the field of urban planning on earthquake resistance and hazardous prevention, building a powerful Spatial Decision Support System for Urban Planning on Earthquake Resistance and Hazardous Prevention. The system provides a comprehensive and intelligent network decision-making platform for urban region disaster prevention plan, avoids the trouble of secondary development with high application value. In addition, according to national data standards and related specifications, we have constructed the spatial database for the urban planning on earthquake resistance and hazardous prevention, and used the production-based knowledge rules to represent relevant knowledge and model used for the urban planning on earthquake resistance and hazardous prevention. Meanwhile a knowledge rule base has been built, facilitating the management and maintenance of knowledge. As a result, it provided a good data support and a good knowledge support for efficient operation of the spatial decision support system for urban planning on earthquake resistance and hazardous prevention. In the last, It provides a scientific basis for the earthquake disaster assessment and disaster prevention plan in the seismic risk assessment, established a stratified and hierarchical structure for the disaster-causing factor, meanwhile calculated the weight coefficients of the disaster-causing factor with the method of the analytic hierarchy process.
