摘　　要：阿尔金断裂系是由多条断裂组成的、规模巨大的走滑断裂体系,对于其走滑位移近几十年来许多学者用不同的方法进行了测量和估算,但认识很不一致:从250～1050km不等。本文就其中参照地质体进行分析,归纳与总结各种性质参照地质体的可适用性,最后认为阿尔金断裂系位移量应该包括主干阿尔金断裂的走滑位移量400km和该断裂系北西侧断裂的走滑位移量两部分,故总位移量应至少为400km。The Altun Tagh fault system is a huge strike-slip faults system which is composed of a number of faults.Lots of scholars try to measure and estimate it with different methods.However,the amount of displacement has been in dispute. The geologists believe it as 250～1050Km.In this paper,the writer classified the reference geologicbodies,concluded and summed up to validate its applicability to hold that the total amount of its displacement should also conclude the part of its north-west side.In this way,the total displacement should be at least 400 km.
