摘　　要：本文主要根据《黄河黑山峡河段地震地质补充论证工作报告》1,对黄河黑山峡河段大柳树坝址区主要地震地质问题,包括1709年中卫7?级地震的地表破裂带长度,F201断层的规模,坝址区F3、F7断层晚更新世以来是否被F201断层“牵动”,坝址区不同级别断层的深浅构造关系等主要方面的研究进展作一概要介绍。According to ＂Supplement Report on Seismology and Geology of Heishan Valley of Yellow River＂, some main problems regarding to selecting the site of Daliushu Dam are discussed. These problems include： the length of surface rupture caused by Zhongwei earthquake with magnitude 7.5 in A.D. 1709, the size of fault Fa01, whether F3 and F7 have been activated by fault Fz01 since late-Pleistocene, and relationship between faults in shallow crust and faults in deep crust under Daliushu dam site.
