Regional division and construction subjects selection evaluation of emergency joint prevention construction of ship oil spill accidents in port
It is of great significance to establish a regional emergency joint prevention system for port ship oil spill accidents within a certain regional scope for promoting the sharing of emergency resources in the joint prevention area and improving the emergency response capability of ship pollution accidents.Based on the route network among the terminals,the spatial analysis tool of ArcGIS software was used to analyze the time accessibility,and the area of joint defense construction meeting the effective emergency was determined.Furthermore,the factors affecting the construction of regional joint defense were analyzed from the aspects of berth conditions,oil spill accident parameters,cargo throughput,management level,etc.,and the evaluation model for construction subjects of regional joint defense was established based on the principal component-BP neural network method.The results show that the emergency joint defense construction area division method and construction subjects selection evaluation model can objectively reflect the true situation of the evaluation object.In the construction of emergency joint defense,the construction scheme can be selected according to the actual needs and the evaluation results.
