构造应力场,是地球动力学的关键问题,也是地貌学特别是构造地貌学的重要问题。新近发现可用水系分布方向恢复新构造应力场,为用地貌学方法研究这一问题开辟了新途径。 水系也如其他地貌现象一样,是内营力和外营力相互对抗作用的产物。表现在排列 The tectonic stress field is a key issue of geodynamics and an important issue of geomorphology, especially tectonic geomorphology. Recently, it is found that the new tectonic stress field can be recovered by the direction of distribution of water system, which opens up a new way for the study of this issue by geomorphology. Like other landscapes, the water system is also a product of the mutual antagonism between internal and external operations. Performance in the arrangement
