中文摘要：

地貌和新近系位错测量的方法是获得活动断裂在新近纪晚期以来可靠和准确的运动学数据的正确方法，本文结合遥感、地貌、变形测量与新近纪测年等手段，重点研究了伊犁盆地喀什河断裂中更新世以来的垂直活动速率。喀什河断裂在中更新世以来的新活动主要表现在河流阶地和地层的位错，综合研究了这些位错数据，分析了断裂各段在中更新世以来的活动速率，讨论了1812年尼勒克地震的平均位错反映断裂现今最新的活动速率，提供了喀什河断裂中更新世以来不同时期活动的定量数据，填补了天山内部新近纪晚期研究的部分空白，对现今地壳运动与地球动力学研究及减轻地质灾害有重要意义。

英文摘要：

The methods of geomorphology and the measurement of new dislocation on active fault are reliable and accurate techniques for obtaining the activity of fault since neocene. In this paper, combining the methods of remote sensing, geomorphology, deformation measurement, and chronolometry, the vertical active rate of Kashi River fault in Yili basin since middle Pleistocene is studied emphatically. The new action of Kashi River fault since middle Pleistocene is represented as the river bench and dislocation of strata. The dislocation data are comprehensively studied. The active rate of each segment of the fault since middle Pleistocene is analyzed. And the last active rate of the fault represented as the average dislocation of Nileke earthquake in 1982 is discussed. The result provides the quantitative data of Kashi river fault action in different epoch since Pleistocene and fills the gaps of the research on the Tianshan interior in later neogene. This result is significant for research on the crust movement and the earth dynamics, as well as reducing the geological disaster.
