| 摘 要： | 贵德盆地作为青藏高原东北部的一个构造地貌单元，盆地中河流阶地发育，但是阶地的形成时代仍存在很大争议.选择阶地作为研究对象，并从龙羊峡至松坝峡共采集阶地样品10个，进行ESR测年，对测试结果进行了分析研究，建立了T0-T4阶地的海拔、河拔高度序列，分析了贵德盆地新构造运动规律具有间歇性、差异性、不对称性特征.

| Abstract: | The Guide Basin, a tectonic landform unit in the northeast Qinghai-Tibet Plateau, is well developed with river terraces. However, much controversy still exists regarding the age of the river terraces. By testing and analyzing the ESR age data of 10 samples from the river terraces in Guide Basin from Longyang Gorge to Songba Gorge, it is preliminarily concluded that the uplift of the Yellow River Basin in Guide area is characterized by intermittence, multi-period heterogeneity and asymmetry. |
