| 摘 要： | 试图通过水系、构造和现代资料的反演来对祁连山中段中晚更新世以来及现代构造应力场特征的研究，来表明构造应力场具有明显的分区性，且主压应力方向由北向南发生渐变，角度逐渐增大。

| Abstract: | In an effort to study the characteristics of tectonic stress fded of middle section of Qilian Mountain since middle and later Pleistocene to that of present, reversion analysis on drainage system, tectonic and present evidences is carried out. The results show that there is clear tectonic stress field division in the region and the orientation of the principal compressive stress gradually increases from north part to south part of the region. |
