| 摘 要： | 本文利用重力资料,采用单层地壳模式反演了甘肃西部地区的地壳厚度。根据艾利的均衡假设,进行了均衡补偿的归算,编制了莫霍界面图和均衡异常图。作者对甘肃西部地区的地壳变异带形成的力源进行了简要的探讨,结合历史地震资料,讨论了地壳构造、均衡异常与地震的关系。

| Abstract: | In this paper, the crustal thickness of the western region of Gansu province is inverted by means of gravity data and single crustal model. According to Airy isostatic hypotheses, a computation of isostatic compensation has been made and a map of M surface and a map of isostatic anomaly drawn up.The force source formed on the crustal variation belt of the western region of Gansu province is briefly discussed.In the light of the historical data of earthquakes, the relationship between crustal structure and isostatic anomaly and the earthquakes is discussed. |
