根据辐射沙脊群中部条子泥两翼沿海自建的4座潮位遥测站的实测记录，2012年10月17日新条鱼港站观测到了9．39 m 的特大潮差，不仅证实了20世纪80年代小洋口海域9．28 m 的潮差记录的可信性，而且刷新了此海域最大潮差记录。基于移动驻潮波和动力地貌理论，本文采用潮位实测分析、二维水动力数值模拟和潮滩地貌遥感解译等方法，阐述了特大潮差的动力成因及其地貌响应机理，提出了条子泥二分水同步潮位跳绳效应，从理论上分析了该海域实测特大潮差的合理性。如若改变最大潮差统计方法，该海域最大潮位差可达9．62 m，关于辐射沙脊群对重新认识辐射沙脊群及中国沿海极值潮汐特征更具有创新价值。

The largest tidal range 9.39 m was observed on October 17,2012 at Xintiaoyugang station which is one of 4 tide-gauge stations along coast of the radial sand ridges,southern Yellow Sea.It confirms that the historical tidal range 9.28 m in Xiaoyangkou in 1980's is reliable and the largest tidal range record in this sea area is renewed. Reasons of the largest tidal range are expressed from two aspects.One is"movable standing tidal wave"that is the hydrodynamic cause by hydrodynamic simulation modeling.The other is"the water diversion"(Erfenshui)that is the dynamic geomorphic reason by remote sensing interpretation.As the results,"Jump Rope"effect of the syn-chronous water level along Tiaozini tidal flat and the largest tidal range of 9.39 m is reasonable and effective.Even more,the maximum tidal range in this area could be 9.62 m if statistical method can be changed.The largest tidal range of radial sand ridges in this paper has reference value and innovation of the tidal characteristics in the whole coast of China.
