山区河流阶地变形的研究在分析山区构造活动,特别是评价地震活动性时得到实际运用。要弄清阶地综合体结构与构造运动时空状态间的一致性有一定的困难:阶地形成机制与较古阶地面的破坏过程有关,同时所产生的阶地级数的不完整和河谷中阶地面的残缺不全使深入研究同年代阶地及测量其变形大小的可能性降低,迄今很少有人研究河流阶地的高度和相应构造运动大小间的关系,如在相同类型的构造区内阶地高度与穿过这些格架的河流长度有
The study of terrace deformation in mountainous river terrains has been practically used in the analysis of tectonic activities in mountainous areas, especially in the evaluation of seismicity. It is difficult to ascertain the consistency between the terraced complex structure and the temporal and spatial state of tectonic movement. The formation mechanism of terraces is related to the destruction process of the ancient terraces, and the incompleteness of the terraces and terraces Incompleteness makes it impossible to further study the same grade and to measure the deformation size. So far, there has been little research on the relationship between the height of the river terrace and the size of the corresponding tectonic movement. For example, in the same type of tectonic zone, The length of the river there is
