中文摘要：
简述了在南海纳土纳岛（Natuna Islands）建设地震台站的意义和设备.用获得的首批观测资料,分别采用接收函数方法和ScS波分裂技术反演了纳土纳地震台下面地壳的S波速度结构和各向异性参数.结果表明纳土纳地震台下方地壳厚度约28km,为典型的陆壳性质,上地幔40～50km为低速层.纳土纳的地壳快波方向为S62°E,与GPS测量的亚洲南部巽他块体的地壳运动方向一致.
英文摘要：
The building process of a new seismic station in Natuna Islands is introduced, including its significance and its infrastructure and equipment. Based on primary observation data, we use receiver function method and SoS-wave Splitting technique to inverse the S-wave velocity structure and anisotropy parameters of crust under the Natuna Station spectively. The results show that the crust beneath Natuna Station is typical continental crust of 28kin thick, and there is a low velocity layer （buried depth of 40-50 km） in the upper part of the mantle. The polarization of fast wave is S62°E （North clockwise 118°）, identical to that of Sundaland, Southeast Asia, determined by GPS measurements of the crustal movement.
