As global climate change intensifies, the po Marine business work, disaster reduction, disaster prevention, spatial analysis, risk synthesisability of marine disasters becomes greater and greater. In order to reduce the damage caused by marine disasters and to be able to shoulder the responsibility of major powers in facing marine disaster risks, China needs to establish China’s domestic marine disaster prevention and relief system and international cooperation mechanism for disaster prevention. On this basis, a preliminary idea for establishing a disaster risk assessment system was proposed. After the system is completed, the spatial analysis function based on GIS, combined with the disaster risk assessment database, can quickly, practically and accurately provide special disaster risk results for disaster prediction and prediction of relevant departments and select effective and scientific disaster prevention, mitigation and relief Measures provide the basis.
