摘要
本文应用卫星测到的2～30阶球谐函数系数(GEM8) 计算了台湾海峡及邻近地区的岩石圈层下地幔流应力场。在比较了该区域的构造地质以后,发现应力场的方向,尤其是在板块收敛区域的甚高阶场(26～30阶)的方向与在菲律宾海和南海等区域的板块运动方向一致。
In the paper, we apply the 2-30 degree harmonic coefficients (GEM8), which are determined by satellite measurements, to calculate the stress field of mantle convection currents under lithosphere in the Taiwan Strait and its adjacent region. After comparison with tectonic geology in this region, we can find the directions of stress field are coincident with that of plate movement in Philipines Sea and the South China Sea region, especially more high degree' s gravity field (26-30 degree) in the plate convergence region.
