摘　　要：通过2007—2008年西南季风期间茂名海浪等环境要素观测资料,对该地区的拍岸浪进行了统计分析,结果表明拍岸浪高的分布基本服从瑞利分布,低频长波偏差大;拍岸浪波高与水深之比集中在0.5—1.16之间,其平均值为0.783,波浪破碎判数γ与理论值非常接近。通过各要素与拍岸浪浪高的相关性分析,发现近岸浪的波高、周期以及百米塔的风速与拍岸浪浪高成较好的正相关。Based on the 2007--2008 meteorological observed data of environmental elements like sea wave in Maoming during the southwest monsoon period, this paper made a statistical analysis on the surf characteristics in Maoming inshore sea area. Results showed that the distribution of the surf high obeys the Rayleigh distribution, with large deviation in low frequency wave length; surfheight and wave breaking depth ratio was 0.5--1.16, with an average value of 0.783, the wave breaking criterion y was very close to the theoretical value. Through correlation analysis between the meteorological data and the surf wave, a good positive correlation between surf wave elevation and the nearshore wave height, period and the wind speed was founded.
