摘　　要：从深水区域传播到近岛礁区域的波浪,由于复杂的珊瑚礁地形地貌,波浪谱的特征与深远海有很大差别。论文以西沙某岛礁泻湖内区域的台风波浪谱实测资料为基础,对常用的Ochi-Hubble谱在近岛礁海域的适用性进行评估,考察近岛礁双峰谱影响参数的变化特性,获得混合浪风浪和涌浪成分的参数拟合式,为后续南海近岛礁海域波浪谱特征的准确描述奠定基础。When waves propagate from deep water area to the area near the island reef^characteristics of wave spectrum will be varied significantly.Based on the in-situ experiment data of wave spectrum in typhoon season in a lagoon near islands and reef in the Xisha,applicability of Ochi-Hubble spectrum in this area is investigated.Influence parameters in the bi-modal spectrum model are varied to fit the mixed waves composed of wind wave and swell in waters near islands and reefs,which lays a foundation for accurate description of wave spectrum in the lagoon near islands and reefs in the South China Sea.
