摘　　要：台风是造成橡胶风害的主要原因之一,为确定广东省橡胶风害关键因子、等级标准和风险区域。本文采用个例分析法结合文献资料、灾情调查资料、气象观测资料和GIS技术确定了广东橡胶风害的等级标准、关键致灾因子和风险区划。结果表明:瞬时极大风速对橡胶风害的发生起关键作用。橡胶风害主要分为无风害(≤8级)、轻度风害(9~10级)、中度风害(11~12级)和重度风害(>12级)4个等级。区划结果表明:无风害区主要位于粤北北部地区,轻度风害风险区主要位于粤北、粤中大部和粤西北部地区,中度风害风险区主要位于粤东和珠三角地区,重度风害风险区主要位于粤西南部。Wind damages especially caused by typhoon is one of the main meteorological disasters to rubber trees in Guangdong.So it is important to study main disaster-causing factors,wind disaster grade criterion and risk distribution.Based on GIS and statistical analysis of observed wind data,investigated wind disaster data and published research papers,We comprehensively investigated the grade criterion,key disaster-causing factors and risk zoning of wind disasters in Guangdong.The results showed that:The key factor of rubber wind damages caused by typhoon was instantaneous maximum wind speed,which can be used to determine the grade criterion in wind disasters.According to instantaneous maximum wind-speed scale,there were four risk degrees:no risk(less than 8 wind scale),low risk(9~10 wind scale),medium risk(11~12 wind scale)and high risk(>12 wind scale),can be classified to describe the rank of rubber wind disasters.And risk zoning results revealed that:No risk areas were in the north part of northern Guangdong and low risk areas covered most part of northern,middle and north part of western Guangdong.Medium risk areas were mainly in Pearl River Delta and eastern Guangdong and high risk areas were in the southwest of Guangdong.
