Study on Urban-disasters Composite Risk Assessment Database
In the research of urban-disasters composite risk assessment,data is the most basic element.Accurate,comprehensive,high quality data is essential to ensure the accuracy of disaster analysis and disaster risk classification.The systematic methods of data acquisition,processing and management and analysis need to be studied.In this paper,based on the analysis of characteristics of urban-disasters composite risk assessment data,the risk assessment database is designed.Data standard and database eonstruetion standard are proposed.According to processing phase,the database is divided into four sub-databases:gathering database,general database,study area database and history database.The logic and physic design for all the databases are discussed.The updating mechanism is built for the database and continuance updating is realized.
