图5 构造挤压作用对山前冲积扇发育的影响（据参考文献[79]修改） 盆地冲积扇构造体系记录了流域的构造隆起与地层褶皱之间的关系；地层楔入前生长地层表明构造抬升是同沉积过程，冲积扇的沉积过程记录了其褶皱变形作用

Fig.5 Cross-section showing the influence of tectonic compress on the development of alluvial in the piedmont (modified after reference[79]) The alluvial fan system records the relationship between tectonic uplift and stratigraphic fold in the basin. The formation wedge into the former growing strata indicates that the tectonic uplift is a syndepositional process and its folding deformation is recorded in the deposition process of alluvial fan
