摘　　要：根据1949-2017年广东省登陆热带气旋最佳路径数据以及1994-2016年广东省重大热带气旋灾害资料,对登陆广东省热带气旋的时空分布特征及其影响进行了统计分析。结果表明:广东省登陆热带气旋频数的年际变化明显,总体上呈下降趋势。7-9月是广东省热带气旋登陆的高频期,登陆地点主要集中在湛江、汕尾、阳江、江门。登陆广东省的热带气旋主要来自南海北部和菲律宾以东洋面;其中登陆最多的是强热带风暴,其次是热带风暴和台风。The characteristics and impacts of tropical cyclones landing in Guangdong province are statistically analyzed based on the best path data from 1949 to 2017 and the data of major tropical cyclone disasters from 1994 to 2016.The results show that the landing tropical cyclones have obvious interannual variability with a overall decrease trend.The tropical cyclones make landfall in Guangdong province most frequently in JulySeptember,,and the landing locations are mainly in Zhanjiang,Shanwei,Yangjiang and Jiangmen.The tropical cyclones landing in Guangdong province mostly generated in the northern South China Sea and the Pacific Ocean east of Philippines.The tropical cyclones landing in Guangdong province are mainly strong tropical storms followed by tropical storms and typhoons.
