摘　　要：通过对礼乐盆地构造沉降和总沉降变化的分析,结合盆地地质构造发育的特点,将盆地构造沉降幕式变化与盆地构造演化紧密关联起来,认为盆地的三幕构造沉降与盆地三个构造层的特点和形成演化的三个阶段相对应。同时,论述了区域构造运动与盆地构造沉降、构造特征、形成演化、沉积特征之间的内在联系,揭示了构造活动对沉积的控制作用。In this paper the subsidence history of Liyue Basin was simulated and the changes in tectonic subsidence was analyzed. The results show that the episodic change in tectonic subsidence was closely related with basin evolution, and the three stages of tectonic subsidence correspond well to the three structure layers and the three stages of basin development. Additionally, the inherent relation of tectonic activity and tectonic subsidence with the structural characteristics, basin evolution, sedimentary characteristics was discussed, and it was found that the regional structural activity controls the sediment development.
