摘　　要：本文根据南海及邻域的岩石圈动力学环境，把新构造类型划分为离散型、聚敛型、平移型和滑动型。依据构造不整合、地层缺失、断裂、变形、变质及火山活动等构造事件，提出本区新构造始于晚渐新世的新认识，详细分析了本区新构造运动的脉动性及造陆、造山、造海、造盆等性质，并对其构造演化与动力学模式进行初步的探讨。According to the environments of lithospheric dynamics in the South China Sea andits adjacent regions,the neotectonism is classified into divergence,convergence,strike-slip and gliding types.Through tectonic events such as tectonic unconformity,strati-graphic break,fault,deformation,metamorphism and magmatism,we begin to know thatneotectonism of the area began in Late Oligocene.And also the pulsation and natures ofepeirogeny,orogeny,sea and basin- building of neotectonism in the area are analysed.And its tectonic evolution and dynamics model of the South China Sea is preliminarilydiscussed.
