Method for evaluating risk of sea level rise and storm surge to coastal agricultural area

Abstract

The invention discloses a method, device and equipment for evaluating the risk of a coastal agricultural area by sea level rise and storm surge and a computer readable storage medium, and the method comprises the steps: dividing a to-be-evaluated coastal area into a plurality of to-be-evaluated units; calculating a sensitivity quantity value and an adaptability quantity value of each unit to be evaluated; and determining the risk level of the to-be-evaluated area according to the sensitivity quantity value and the adaptability quantity value, taking coastal agricultural area risk evaluation as a target, comprehensively considering double risk influences of sea level rise and storm surge, and meanwhile, considering the adaptability of the coastal area, so that the evaluation result is more objective and credible. The quantitative evaluation method also makes the result more scientific and reliable.

Description

Technical field [0001] The present invention relates to the field of marine disaster prediction assessment, in particular to a sea level rise and storm tide to assess the risk of coastal agricultural regional risks, devices, equipment and computer readable storage media. Background technique [0002] The rise of sea levels raised in global climate change will result in low land, storm tide, and a series of ecological environment in coastal erosion. The agricultural system in coastal areas will further lead to frequent floods in the future, which will seriously affect agricultural production systems and production capacity, which cause great threat to the natural environment and socio-economy. Therefore, the assessment of the rising coastal agricultural areas and the impact of storm tide disasters is necessary to develop in the future. [0003] At present, the relevant assessment method has lacks targeted, and has been biased toward the comprehensive land assessment. It lacks the ...

AI Technical Summary

Problems solved by technology

[0003] At present, relevant assessment methods lack pertinence. Existing assessment methods are biased towards comprehensive land assessment, and lack of risk assessment methods specifically for coastal agricultural areas, resulting in insufficient effectiveness and imperfect consideration of risk factors. Existing assessment methods lack comprehensiveness. Considering the double impact risk of sea level rise scenario and storm surge and result in underestimated risk

In summary, the existing assessment methods cannot meet the needs of future production and development in coastal agricultural areas in terms of pertinence and accuracy, and there are certain limitations in assessment techniques
