摘　　要：2003年2月24日新疆巴楚—伽师交界地区发生了MS6.8地震。地震的发生除了对建筑物及构筑物与水利、交通、电力、电信设施造成了不同程度的破坏外,在地震烈度Ⅶ度以上(包括Ⅶ度)地区产生了不同程度的地震地质灾害。地震地质灾害主要为场地砂土液化、地裂缝与河流陡岸滑塌等类型。随后在新疆巴楚—伽师6.8级地震灾区开展了地震小区划工作,对Ⅶ、Ⅷ、Ⅸ度区进行了场地工程地质条件勘测与综合评价,判定该地区未来可能产生的主要地震地质灾害为场地砂土液化、河流陡岸滑塌。There occurred Ms6. 8 earthquake on Feb. 24,2003 in the common boundary of Bachu and Jiashi county, Xinjiang. The earthquake caused geological disaster in some ways in seismic intensity ≥ Ⅶregion except that damaged buildings and constructions, irrigation works, traffic, electric power and telecommunication equipments in some degree. Seismogeological disaster shows sand liquefying in the field, ground cracking and steep river bank collapsing etc.. China seismological bureau designated seismological bureau of Xinjinag Uygur autonomous region to carry out seismic micro-regionalization in stricken-region of Bachu-Jiashi earthquake of Ms6. 8 in 2003. By exploring field engineering and geological conditions and assessing synthetically in stricken-region with the intensity Ⅶ, Ⅷ and Ⅸ, we think that future main seismogeological disaster are maybe field sand liquefying and steep river bank collapsing etc. in the region.
