摘　　要：利用1999—2012年中国地壳运动观测网等网络的GNSS观测资料,获取了鄂尔多斯块体及其周缘地壳水平运动速度场和应变场,分析了该区域的整体的运动趋势和应变特征,讨论了该区域地壳水平应变场分布特征与地震分布的对应关系。Based on the GNSS observation data of the Chinese Crustal Movement Observation Network from 1999 to 2012,the horizontal crustal motion velocity field and strain field of the Ordos block and its periphery are obtained.The overall movement trend and strain characteristics of the region are analyzed,and the corresponding relationship between the distribution characteristics of the crustal horizontal strain field and earthquake distribution in this region is discussed.

关 键 词：GNSS 速度场 应变场 地震分布
