Abstract: Typhoon disaster has a great impact on China's social and economic development. It is of great significance to study the characteristics and causes of typhoon disaster for typhoon prevention and disaster reduction. Taking the No.1513 Typhoon "Soudelor" as an example, through the field investigation in Fujian Province, it is found that the disaster situation in the coastal areas of northeast Fujian is serious, the proportion of agricultural disaster is large, and the loss of agriculture, forestry, animal husbandry and fishery is serious. The main factors causing severe typhoon disaster are the big gap of standardized seawalls and other infrastructure, and the weak organization system of typhoon prevention at the grassroots level. Therefore, it is necessary to improve the typhoon prevention engineering system in coastal areas and strengthen the construction of coastal wind prevention infrastructure on the basis of improving the typhoon prevention plan system.
