近岸海水贝类养殖的渔业灾害风险评估方法与系统

By combining comprehensive data collection and dynamic vulnerability index algorithms with the analytic hierarchy process (AHP), the dynamic risk value of nearshore marine shellfish aquaculture is calculated. This solves the problems of incomplete data coverage and static risk calculation in existing technologies, enabling accurate risk assessment and protection recommendations, and improving the disaster prevention capabilities of the aquaculture industry.

AI Technical Summary

Technical Problem

Existing disaster risk assessment technologies for nearshore marine shellfish aquaculture suffer from incomplete data coverage, imprecise parameter selection, static risk calculations, and a lack of specific protective recommendations. This results in significant discrepancies between the assessment results and actual risks, failing to meet the aquaculture industry's need for precise disaster prevention.

Method used

Through comprehensive data collection, data preprocessing, and parameter screening, combined with the dynamic vulnerability index algorithm and the analytic hierarchy process, dynamic risk values ​​are calculated, and targeted protection recommendations are output. This includes the integration of aquaculture logs, periodic sampling tests, and environmental monitoring data, the calculation of dynamic vulnerability index and external environmental risk index, and the synthesis of risk values ​​from the internal and external factor product model.

Benefits of technology

It achieves full-dimensional data coverage and dynamic risk quantification, provides accurate protection recommendations, improves the accuracy and effectiveness of disaster prevention and control, and ensures that the assessment results match the actual risks.
