Storm surge vulnerability evaluation method and device based on multiple factors, and computer equipment

Abstract

The invention relates to a storm surge vulnerability evaluation method and device based on multiple factors, computer equipment and a storage medium. The method comprises the following steps: determining a storm surge influence area according to historical storm surge data; dividing the storm surge influence area into a plurality of grids with preset sizes by adopting a fishing net creation methodin a geographic information system; obtaining geographic environment attribute information of each grid by using a geostatistical analysis method in the geographic information system; according to the geographical environment attribute information of each grid, determining vulnerability evaluation factors of each grid, wherein the vulnerability evaluation factors comprise an exposure degree factor, a social and economic factor, a land utilization factor, an ecological environment factor, a coastal structure factor and a disaster bearing capacity factor; and according to the vulnerability evaluation factor, determining a vulnerability index of each grid, the vulnerability index being used for representing the difficulty degree of damage caused by storm surge. By adopting the method, the precision of the vulnerability index of the storm surge can be improved.

Description

technical field [0001] The present application relates to the field of computer application technology, in particular to a multi-factor-based storm surge vulnerability assessment method, device, computer equipment and storage medium. Background technique [0002] With the development of computer application technology, storm surge vulnerability assessment technology has emerged. Storm surge is a disastrous natural phenomenon. Due to severe atmospheric disturbances, such as strong winds and sudden changes in air pressure, the sea water rises and falls abnormally, and at the same time superimposes on the astronomical tide. form a stronger destructive force. The vulnerability assessment of storm surge refers to the chance of the affected body being damaged by the storm surge disaster and the difficulty of damage. [0003] In the traditional technology, when determining the vulnerability index of storm surge, there is a problem of low precision of the vulnerability index of s...
