Abstract

Pang, S.; Li, S., and Hu, X., 2020. Typhoon carrier disaster loss index models and application based on principal component analysis. In: Yang, D.F. and Wang, H. (eds.), Recent Advances in Marine Geology and Environmental Oceanography. Journal of Coastal Research, Special Issue No. 108, pp. 68–72. Coconut Creek (Florida), ISSN 0749-0208.

This paper focuses on the formation and harm of typhoons and impact on direct economic losses in Guangdong Province of China. It specifically considers three carriers of typhoons: fragility of disaster-bearing body, hazard factor intensity, and the capacity of disaster prevention and alleviation. Based on the three carriers, the index system of impact of typhoon disaster on social economy, natural geography, and disaster prevention and alleviation data, such as per capita GDP, typhoon t index, soil porosity, and number of special emergency plans for typhoon, is built. Using the principal component analysis method, correlation analysis and characteristic index extraction are performed for 25 impact indicators, three carrier index models of typhoons are innovatively established, and the typhoon disaster loss index model is further proposed and established, which is used to calculate the loss index of 54 typhoons in Guangdong from 2001 to 2018 for application analysis. This study provides scientific reference for typhoon disaster prevention and emergency rescue plan optimization.
