摘要
本文根据东经１００°～１７０°，北纬０°～５０°的西北太平洋海域，１９３０年～１９９０年的大量海洋和气象资料，以深海等压面１０００，１５００，２０００，２５００和３０００ｄｂ为依据，按动力学原理，计算了面积约３０００多万平方公里广阔海域的动力深度及其偏差，并以标准海面为基准，绘制了迄今最为精细的海面动力地形图。通过与全球海面动力地形的比较，研究了该海域的起伏特征，发现了苏禄海盆地及其周围海域海面起伏的异常区，初步研究了它的形成机制。
On the basis of a large amount of oceanic and meteorological data of Northwest Pacificarea（long. 100°～170°E，lat．0°～50°N）collected during 1930-1990，the dynamic depth andit’s deviation of this vast area（more than 30 000 000 km^2 in total）have been computed ac-cording to dynamics principle by referring to deep-sea isobar surfaces of 1 000， 1 500， 2 000,2500 and 3 000 db．Moreover， maps of sea surface dynamic topography have been plotted bytaking the standard sea surface as datum，these are the finest maps thus far appeared，Theundulating features of the sea surface dynamic topography of the area have also been investi-gated by comparing with global one，We discovered anomalous undulating features in Sulusea basin and it，s surrounding area. Preliminary research on the mechanism of their forma-tion has been made.
