摘要: 利用西太平洋地区的雅浦-马里亚纳海沟附近海域的多波束水深数据,获得了9.8°N—13.2°N、132.2°E—145°E矩形区域内的高精度水深地形图。通过对精细地貌进行研究发现,马里亚纳海沟南部的洋坡上发育有大范围的地垒、地堑型地貌,雅浦海沟北部存在明显的分段性特征,菲律宾海盆和帕里西维拉海盆内存在不同展布方向的大规模脊-槽地貌。研究结果表明此处复杂的地形地貌特征主要受板块运动的控制。最后结合已有研究成果,对该区域的地形地貌进行了分类。

Abstract: Based on the multi-beam bathymetric data of the Yap-Mariana Trench in the Western Pacific Ocean, the high-precision bathymetric topographic maps in the rectangular areas of 9.8°N-13.2°N and 132.2°E-145°E were obtained. Then the detailed geomorphologic analysis shows that there are large-scale horst-graben geomorphology on the slope of the southern part of Mariana Trench, obvious segmentation in the northern part of the Yap Trench, and large-scale ridge-trough geomorphology in different distribution directions in the Philippine Basin and the Parece Vela Basin. The results show that the complex topographic and geomorphological features are mainly controlled by plate motion, and the topographic and geomorphological features of the region are classified according to the published research results.
