Regional storm surge destructive evaluation method and system based on short-term tide level and long-term meteorological data

The invention discloses a regional storm surge destructive evaluation method and system based on short-term tide level and long-term meteorological data, and the method comprises the following steps: collecting typhoon historical path data in a research region, and carrying out the preprocessing of the typhoon historical path data; performing maximum wind speed correction by adopting a composite method based on a decision tree model and an empirical formula; acquiring hourly tide level or high-low tide level in the research area, and calculating storm surge during typhoon by adopting a harmonic analysis method; a random forest method is adopted to construct a typhoon path-water increase relation prediction model, and typhoon paths influencing the research area are screened out; calculating the influence time of the typhoon path, and determining the effective influence range of the typhoon path; and calculating a destructive evaluation index of the tropical cyclone in the research area. According to the method
