Jellyfish disaster risk assessment method

Abstract

The invention relates to the technical field of jellyfish disaster assessment, in particular to a jellyfish disaster risk assessment method. In a risk assessment process, a risk degree numerical value is multiplied by a risk degree numerical value to obtain a specific numerical value of a risk degree, the risk degree is the occurrence possibility and the intensity, risk degree evaluation indexes comprise the disaster-inducing factor risk degree and the disaster-pregnancy factor risk degree, and the vulnerability degree refers to evaluation of the number of damage opportunities of disaster-bearing body factors suffered from jellyfish disasters and the damage difficulty degree, the types of jellyfishes existing in the sea area are analyzed, in combination with investigated conditions of temperature, plankton, growth foundation, ocean current and the like in the existing environment, a model establishment method is adopted, the number of jellyfishes in a period of time in the future is predicted, the disaster is further evaluated to obtain the risk degree, and the jellyfish disaster can be early warned in advance, found and reminded as early as possible to reduce the influence of the jellyfish disaster as far as possible.

Description

technical field [0001] The invention relates to the technical field of jellyfish disaster assessment, in particular to a jellyfish disaster risk assessment method. Background technique [0002] At present, there are no relevant reports on the risk assessment of jellyfish disasters at home and abroad. With reference to other geological disaster risk assessment and zoning studies such as red tide disaster risk, storm surge disaster risk zoning, and gale disaster risk, all indicators are screened under the condition that the data are available. However, the evaluation of the risk of ecological disasters needs to be based on the understanding of the causes of disasters, the process of disasters, and related environmental factors. However, for jellyfish disasters, the source of jellyfish, disaster outbreak mechanism, key control factors, and living habits of jellyfish are currently being studied, and there are some research results, but there is still a lack of actual verificatio...

[0002] At present, there are no relevant reports on the risk assessment of jellyfish disasters at home and abroad. With reference to other geological disaster risk assessment and zoning studies such as red tide disaster risk, storm surge disaster risk zoning, and gale disaster risk, all indicators are screened under the condition that the data are available. However, the evaluation of the risk of ecological disasters needs to be based on the understanding of the causes of disasters, the process of disasters, and related environmental factors.

However, for jellyfish disasters, the source of jellyfish, disaster outbreak mechanism, key control factors, and living habits of jellyfish are currently being studied, and there are some research results, but there is still a lack of actual verification in natural sea areas.
