在野外观测与遥感综合解译的基础上，充分利用区内已积累的地质与地球物理资料，应用统计分析方法，从７个方面分别计算分析了汾渭与贝加尔裂谷系的相似性系数。显著性统计检验表明，两裂谷系在几何形态、三维构造格局、历史与现今活动性各方面都存在显著的相似性。结合空间测量与两裂谷系现今构造应力场的实测资料分析，推断汾渭与贝加尔裂谷系高度相似性产生的动力学机制与东亚大陆这一地带南、北块体间不等速西向运动所造成的大规模Ｓ形张裂作用存在成因联系。
Based on the comprehensive interpretation of field observation and remote sensing, the similarity coefficient of Fenwei and Baikal rift systems was calculated and analyzed from seven aspects by making full use of the accumulated geological and geophysical data in the area and using statistical analysis methods. Significant statistical tests show that the two rift valley in the geometry, three-dimensional structure, history and present activities in all aspects of significant similarity. Combining with the spatial measurement and the data analysis of the present tectonic stress field in the two rift systems, it is inferred that the dynamic mechanism of the high similarity between the Fenwei and Baikal rift systems and the non-constant westward movement of the south and north blocks in the East Asian continent The resulting large-scale S-shaped cracks exist causal link.
