摘　　要：从深水海域传播到岛礁海域的波浪,由于复杂的珊瑚礁地形地貌,波高周期的联合分布特征与深远海有很大差别。论文以南海岛礁海域的实测波浪资料为基础,基于B样条构型拟合得到波高周期联合分布特征。拟合和实测结果的对比表明,采用基于B样条构型拟合波高周期联合分布的方法适用于岛礁海域波浪统计特征的描述,为后续南海岛礁海域长期波浪条件特征的精确描述奠定了基础。When waves are from deep water to islands and reefs,joint distribution of wave heights and periods will be varied greatly.Based on wave data measured in the South China Sea,joint distribution of wave heights and periods is obtained by using B-spline approximation.It is shown that the B-spline function is suitable for evaluation of wave conditions around islands and reefs,which will lay a foundation for an accurate description of long-term wave conditions around islands and reefs in the South China Sea.
