Marine disaster risk event classification method and device

Abstract

The invention relates to the field of geographic information technology, in particular to a marine disaster risk event classification method and device, the method includes searching for the reliability and probability corresponding to the marine disaster risk event, Then, according to the reliability and the possibility, the membership value of the marine disaster risk events under different preset categories is calculated, and the preset category with the largest membership degree is selected as the category to which the marine disaster risk events belong, so as to realize the classificationof the marine disaster risk events. Because each category has special assessment methods, management strategies and the participation of relevant personnel, marine disaster risk events can be easilyclassified and handled in the corresponding way to prevent and deal with marine disasters, which is more streamlined and improves the efficiency of risk management.

Description

technical field [0001] The invention relates to the technical field of geographic information, in particular to a method and device for classifying marine disaster risk events. Background technique [0002] China's coastal areas are densely populated and cities are concentrated. They are one of the most economically developed areas in China. They account for 13.6% of the country's land area, create more than 60% of social wealth, and play a leading role in the country's economic development. Because the Pacific Ocean facing the coast of China is the largest ocean in the world, the natural environment of the sea area is complex, and the coastal area is located at the intersection of the ocean and the mainland, which is the frontier of various marine disasters, and the coastal areas of China are the most serious marine disasters. , but also one of the most serious marine disasters in the world. With the rapid development of coastal society and economy, marine disasters have b...

Traditional risk assessment methods are only suitable for risks in the strict sense whose probability of occurrence can be derived from historical data or rigorous models. For risk systems with different degrees of certainty and complexity, regardless of the availability of risk information, the degree of certainty and the degree of controversy, it is unreasonable, unscientific, and even misleading to directly adopt this simplified and strict risk assessment method
