Risk analyzing and processing method based on GIS

Abstract

The present invention discloses a risk analyzing and processing method based on a GIS. According to the method, an information collection system can be used to collect emergency information, field environmental information and our condition information, through information processing, a field situation map is rapidly and automatically plotted in the GIS, and the danger range influenced by an emergency event is determined. Combined with field electromagnetic situation information, meteorological and hydrological information, urban traffic condition information, and urban population information, through important goal intelligent screening, important goal damage analysis, important goal secondary disaster analysis, important goal evacuation region analysis and rescue team assembly deployment analysis, an emergency rescue decision suggestion report and an emergency rescue integrated situation map are generated visually, and a decision support is provided for a command authority to analyze and judge a situation, make up minds and command in real time.

Description

technical field [0001] The invention belongs to the field of emergency decision-making for public emergencies, and in particular relates to decision-making suggestions for risk analysis and emergency capability analysis of major public emergencies. Background technique [0002] With the development of urbanization and industrialization, the dense flow of people and goods, and major public emergencies have brought huge losses to human beings. How to maximize the rapid response and effective control of emergencies has become an important issue for countries in the world today. issues of great concern to the government. [0003] With the construction of urban informatization, population data, evacuation areas, important targets, and rescue forces continue to increase, and the corresponding amount of information increases exponentially. The information on emergency response to public emergencies is complex and changeable. Due to the characteristics of suddenness, complexity, de...

Problems solved by technology

[0003] With the construction of urban informatization, population data, evacuation areas, important targets, and rescue forces continue to increase, and the corresponding amount of information increases exponentially. The information on emergency response to public emergencies is complex and changeable. Due to the characteristics of suddenness, complexity, destructiveness and persistence, the analysis of major public emergencies is not intelligent enough

Based on the above situation, information collection and analysis of dangerous disasters, on-site environment and rescue forces, selection and judgment of important protected targets, damage analysis of important targets and secondary disaster analysis, population evacuation area analysis and rescue force deployment analysis more and more complicated

The traditional management information system still only stays on the functions of input, query, statistics, report printing and other functions based on the database, and it is difficult to meet the risk analysis and emergency decision-making needs of major public emergencies
