简介：Langshan，一座单斜晶的山，自从渐新世，开始高举，围住Hetao盆的西北边缘。活跃正常Langshan范围前面差错的连续活动在Langshan区域形成典型basin-and-range地形并且控制Langshan的地形进化。Langshan是一个理想的地方学习在量的geomorphological索引和活跃变丑之间的关系。根据knickpoints上的学习，在纵的隧道侧面和险峻索引上适合，我们证明隧道的规范的险峻索引的分发上的主要控制因素不是气候(降水)，岩性学，沉积流动，而是构造因素，或Langshan范围前面的活动指责。在东南胁腹的短隧道，其长度比16km短，可能仍然在非稳定的地位。如果不认为这些是短隧道，沿着Langshan范围前面差错的规范的险峻索引的分发象M形状模式一样出现，当在中间的节的规范的险峻索引比在两结束的那些高时。这个模式与Langshan范围前面差错的几何分割模型很好一致。在Langshan范围前面差错上联合以前的活跃构造研究，它表明Langshan范围前面差错在连接的阶段，我们现在相当推断Langshan范围前面差错是连接的结果两个都指责哪个双边地连续地独立地延长了。我们的构造geomorphological学习也支持Langshan范围前面差错在连接的阶段的结论。因为两个独立差错的连接，几knickpoints的形成可能被滑倒率变化由于构造因素引起了。基于上面的认知，我们也求婚了地质并且geomorphologicalLangshan范围前面差错的进化模型后来渐新世。
