利用北天山中段地区主要活动断裂关键构造部位测得的断层滑动数据，采用断层滑动资料反演构造应力张量的方法，确定了该区现代( 最新构造变动时期) 构造应力场的基本特征，结果是: 应力方向表现为近南北向的挤压; 应力结构以逆冲型为主，兼有走滑型。该结果与前人利用震源机制解资料反演得到的区域构造应力场的基本特征一致。两类不同应力资料反演得到的构造应力场特征具有较好的一致性，表明在一个较长的地质时期内研究区的构造应力作用比较稳定。

Using the Sliding Direction Fitting Method to invert the fault slip data measured on the critical tectonic position of the main active faults in the middle-eastern part of northern Tienshan Mountains，we got 17 tectonic stress tensors and obtained the basic characteristics of tectonic stress field in the research area． The inverted result shows that the recent tectonic stress field in middle-eastern part of northern Tienshan Mountains is characterized by near N-S maximum compressional stress，and the stress regime is mainly of reverse slip，with some cases of strike slip． This result inverted from fault slip data is greatly matched with that obtained from focal mechanism solutions in this region and it indicates that the tectonic stress action has good stability in a long geological period time．
