Study On Air-ground Integrated Emergency Management System For Flood And Waterlogging In Mountainous And Hilly Areas

With the continuous change of global climate and the acceleration of urbanization,extreme rainfall events in mountainous and hilly areas have gradually increased,and heavy rain and flood disasters have become one of the main natural disasters affecting the economic development of mountainous and hilly areas and the safety of people’s lives and property.It has become one of the hot and difficult problems in the research and practice of emergency management of flood and waterlogging disaster in mountainous areas to establish the air-ground integrated emergency management system.This paper takes mountain region as the research object,studies the risk suffered by the region when the flood disaster occurs,establishes the air-ground integrated emergency management system in accordance with the identified risk factors,and uses the cloud model to evaluate the disaster emergency management level of this region.In the face of flood and waterlogging disaster in mountainous areas,disaster-bearing body such as rivers,dams,reservoirs,municipal infrastructure and buildings often show typical vulnerability.In this paper,based on the disaster system theory,flood and waterlogging disaster risk in mountainous and hilly areas is analyzed from three aspects:disaster factor,disaster environment and disaster-bearing body,and DEMATEL-ISM(Decision Making Trial and Evaluation Laboratory-Interpretative Structural Modelling)is used to analyze and classify the hierarchical structure of flood and waterlogging disaster risk factors in mountainous and hilly areas and determine the logical relationship between factors.In order to proactively prevent and monitor the risk of flood and waterlogging disaster in mountainous and hilly areas,respond scientifically and reduce the impact of disaster in the case of risk outbreak,an air-ground integrated emergency management system for flood and waterlogging disaster in mountainous and hilly areas is constructed from six aspects: emergency preparedness level,monitoring and early warning and liaison,emergency response level,emergency equipment facilities,rescue professionals and external environment and organizational management.In order to determine the weight of each index of the emergency management system scientifically,the sequential relation analysis method(G1 method)was introduced.In order to determine the emergency management level of flood and waterlogging disaster in mountainous and hilly areas,the five-level evaluation standard was proposed,and the comprehensive evaluation cloud model of flood and waterlogging disaster emergency management system in mountainous and hilly areas was constructed to carry out comprehensive evaluation on the emergency management level of flood and waterlogging disaster in mountainous and hilly areas.The process determines the level of emergency management capacity.Finally,the research results are applied to the evaluation of emergency management level of flood and hilly disaster in the hilly district of Zhengzhou,which proves the scientific characteristics and applicability of the emergency management system,evaluation standard and comprehensive evaluation method.This paper is innovative in the construction of air-ground integrated emergency management system for flood and waterlogging disaster in mountainous and hilly areas,coupling analysis of risk factors of flood and waterlogging disaster in mountainous and hilly areas based on DEMATEL-ISM,proposal of 5-level evaluation criteria for emergency management,and construction of comprehensive evaluation model based on G1 method and cloud model.The research results not only have a certain theoretical significance,but also can guide the construction and dynamic management of the airground integrated emergency management system of flood and waterlogging disaster in mountainous and hilly areas,which has high practical application value.
