摘要： 根据重力场理论,利用最新的全球重力场模型（GGM02C）计算了中国西部各阶卫星重力异常,并对其特征进行了详细的分析。从卫星重力异常中可以看出,中国西部分为新疆和青藏两个大的异常区。主要讨论新疆塔里木重力低带和天山重力高带及天山重力低带;塔里木盆地以北纬40°为界分为南北两个不同的异常区域,并根据卫星重力异常揭示了塔里木存在南北向构造,讨论了形成南北向构造的动力来源。

Abstract: Based on gravity field theory and the newest grace gravity model (GGM02C), the satellite gravity anomalies and characteristics in western China are presented, showing that the western China includes Xinjiang anomalous area and Qinghai-Tibet anomalous area. This paper focuses on the gravitational low belt in Tarim basin and the gravitational high and low belts in Tianshan Mountain. It is suggested that Tarim basin can be divided into two different anomaly areas by north latitude 40°, implying there exist different basement structures in southern and northern Tarim basin. Finally, it is concluded that there exist SN-strike structures in Tarim on the basis of the satellite gravity anomaly, and their dynamic sources are discussed.

Key words: China, west, gravity field model, satellite gravity, Tarim basin, SN-trend structure
