摘　　要：探索地壳运动的动力学特征,着重于地球内部因素的研究,其中侧向压力是地质构造的初始起动力和驱动力,引起地壳内部的应力场变化。文中利用不完全布格重力异常,模拟计算重力场和构造应力场之间的关系,分析了西南一特定区域的地壳运动规律。Explore the dynamics of crustal movement focusing on the factors of the Earth's interior.The lateral pressure is the initial motivation and driving force of the geological structure,can cause the changes of the stress field within the crust.In the paper,the author simulates the relationship between the tectonic stress field and the gravity field and analyzes the crustal movement in a specific area of southwest using the incomplete Bouguer gravity anomalies.

关 键 词：重力异常 应力场 构造应力
