Abstract: Objective/MeaningThe phenomenon of storm surge water increasing caused by strong tropical cyclone activities have brought great disasters to Hainan Island, especially to the northeast of Hainan. This paper explored the impact of storm surge on different regions to alleviate the harm caused by storm surge.Methods/ProceduresTaking Haikou and Wenchang City as the research area, this paper had studied the storm surge water-increasing phenomenon caused by typhoons for many years. According to the indexes of storm surge water level changing, coastal topography, population and socio-economic situation, the study area was divided into storm surge disaster impact zones by using GIS technology.Results/ConclusionsThe results showed that:the lower the altitude, the more vulnerable to storm surge; the gulf area in the study was more vulnerable to storm surge flooding; the densely populated areas were vulnerable to storm surge disaster; the storm surge disaster caused greater losses in economically developed areas.
