摘　　要：本文利用数理统计方法,对登陆我国的热带气旋频数进行分析。发现热带气旋登陆前24、12、6小时近中心最大风速V_1、V_2、V_3分别与登陆后24小时平均最大风速和它们的差值成线性关系。求得了登陆我国台湾、海南、广东、福建四省的V_1、V_2、V_3与/V_1、/V_2、/V_3的回归方程。另外,对登陆我国热带气旋的频数及强度变化进行了气候分析,指出了一些气候特征。The periodic analysis was conducted for the frequency of the tropical cyclones landing on China using the mathematic statistical method. The linear correlation was found between the maximum wind speed near the Center V1, V2, V3 (24hr, 12hr and 6hr before landing) , respectively, and the difference of the mean maximum wind speed (24hr after landing) and V1, V2, Vs (ΔV1, ΔV2, ΔV3) . The regression equations were obtained respectively for the tropical cyclones landing on Taiwan, Hainan, Guangzhou and Fujian provinces of China.
