| 摘 要： | 前陆是指与造山带相毗连的构造相对稳定地区，造山带的岩石向着它俯冲成掩覆，可分为三种类型，即曾为被动型大陆边缘的（Ⅰ型），曾与沟－弧系有关的（Ⅱ型）和陆内造山带前方的（Ⅲ型）。前陆盆地为沿造山带前陆区分布的线状压性深坳陷，可分为周缘前陆盆地，弧后前陆盆地和陆内前陆盆地三种类型。前陆盆地系统是一个沿造山带分布的长条状的潜在沉积可容空间，可划分为楔顶，前渊，前隆和隆后等4个部分。

| Abstract: | The origin and evolution of the concepts, foreland, foreland basin and foreland basin system, are reviewed. Foreland is a relatively stable area near compressive mountain ranges which can be divided into three types, type - I , used to be passive continental margins, type-II ,associated with drench- arc systems and type- III, related to intra- continental mountain belts. A foreland basin can be defined as an elongate, deep depression along convergent mountain. Foreland basins can be classified as peripheral, retroarc and intra-continen-tal(or reactive) foreland basins. A foreland basin system is a system of basins developing along a convergent mountain, which can be divided into wedge top,foredeep,forebulge and back -bulge in a cross section. |
