摘要
根据广东省1949～2000年52年的热带气旋统计资料和减灾防灾年鉴，对登陆广东的热带气旋灾害特征及其形成的灾害链进行了研究。结果表明，登陆广东热带气旋灾害发生频次高，强度大，范围广，突发性、并发性强；具有区域性，季节性，并有集中于某一地区某一时间的特征。由于热带气旋各致灾因子的连锁反应，次生灾害常形成多种灾害链。本文根据灾害链成因对其进行了分类分析。
Base on the data of tropical cyclones in Guangdong in the recent 52 years from 1949 to 2000, the characteristics of tropical cyclones landed in Guangzhou and mechanism of the disaster chains are studied in this paper. The results show that the tropical cyclone disasters in Guangdong occur with high frequency and result in strong impacts in wide area with secondary disasters. They always take place in a constant region and a constant season. Because of the chain interaction of hazards of tropical cyclones, it engenders some secondary disaster chains. The disaster chains are classified in the light of their causes.
