| 摘要: |
| 通过对江苏岸外辐射沙洲动态和西太阳沙海域动力泥沙环境的分析,论述了西太阳沙演变的宏观背景;由实测固定断面资料、地形资料的对比得出近40年来西太阳沙表面形态和水下地形的变化;结合西太阳沙表面泥沙在波浪和波流共同作用下运动特性的水槽试验研究,分析了西太阳沙冲淤变化的动力机制。从“烂沙洋水道-西太阳沙-西太阳沙南水道”系统的角度研究了西太阳沙演变的控制因素和演变规律。 |

| Abstract: |
| On base of the analysis of the trend of radial sand ridges and power-sand circumstance of the sea area, the macroscopical background of the evolvement of Xitaiyangsha is discussed. The data of remote sensing, underwater-fixed profile, and terrain are used to analyze the facial and submarine terrain changes of Xitaiyangsha by the test of the sediments under action of wave and together actions of wave and tide, the dynamics cause of the erode and silt change of the sea area of Xitaiyangsha are analyzed. The factor and law of the evolvement of Xitaiyangsha are also studied from the angle of system. |
