Near-shore storm surge high-precision batch numerical simulation method and system

The invention relates to a high-precision batch numerical simulation method for a near-shore storm surge. The method comprises the following steps: acquiring research data of a to-be-tested region and preprocessing; analyzing the research data of the to-be-tested area, and generating a preset center point; defining a first influence range according to a preset radius by taking a preset central point as a circle center, searching historical typhoons intersected with the first influence range one by one based on the historical typhoon data, calculating the influence duration of the historical typhoons, and generating a typhoon path data set based on the typhoon path, the influence range and the influence duration of each typhoon; generating a simulated storm surge alternative set in combination with the hydrological data of the to-be-detected region; actually measured wind speed data of a coastal meteorological station are collected and corrected, a storm surge numerical simulation model is constructed and trai
