Research on the impact of typhoons on China's socio economic losses
台风对我国社会经济损失的影响研究

摘要

热带气旋（台风）是对沿海地区构成严重威胁的最具破坏性的气象然灾害之一。北太平洋西部的台风约占全球的三分之一，其中很大一部分影响了中国大陆。随着全球变暖，登陆我国的台风对人民生命及财产安全造成的威胁越来越大。本文对我国登录台风在2004-2020年期间的数量、强度、受灾人口、灾害造成的经济损失等数据进行分析。研究发现台风具有明显的季节分布特征；登陆我国频率存年际变化；台风登陆数量和强度在统计期间没有显著趋势特征；台风受灾导致的直接经济损失占GDP的比重在统计期间内呈现下降趋势；受灾地区主要集中在东南沿海地区，尤其广东和福建。研究有助于了解台风灾害对我国社会经济损失的影响，对有针对性的制定台风灾害风险评估模型有参考意义。

Abstract

Tropical cyclones (typhoons) are one of the most destructive meteorological disasters that pose a serious threat to coastal areas. Typhoons in the western North Pacific account for about one third of the world, and a large part of them affect Chinese Mainland. With global warming, typhoons landing in our country pose an increasing threat to people's lives and property safety. This article analyzes the data on the number, intensity, affected population, and economic losses caused by typhoons in China from 2004 to 2020. Research has found that typhoons have distinct seasonal distribution characteristics; The frequency of landing in our country varies from year to year; There is no significant trend in the number and intensity of typhoon landings during the statistical period; The proportion of direct economic losses caused by typhoon disasters to GDP showed a downward trend during the statistical period; The disaster stricken areas are mainly concentrated in the southeastern coastal areas, especially in Guangdong Province and Fujian Province. Research helps to understand the impact of typhoon disasters on China's socio-economic losses and assists in the development of targeted typhoon disaster risk assessment models.
