| 摘 要： | 运用RS和GIS技术，以青藏高原冈底斯地区遥感影像图的制作和水系格局详细解译为基础，结合冈底斯地区线性构造解译，分析了冈底斯地区水系的展布特征和活动构造对水系的控制作用，认为冈底斯地块在新近纪以来随青藏高原整体隆升的同时，区内断隆带和断陷带的隆升速率和强度又有显著差异； 伴随强烈的隆升过程，在地体内发育大量不同性质的近NS向断裂构造，冈底斯地区水系的分布和形态明显受该区新构造运动的控制。

| Abstract: | Based on the RS and GIS technology,the authors mapped the remote sensing images of Qinghai-Tibet Plateau,interpreted and studied the water system of Gangdise block and,in combination with the fault interpretation of Gangdise area,analyzed the distribution characteristics of the water system in the study area.The results show that the water system pattern is controlled by active tectonics.The authors hold that the uplift belt and the rift zone in the Gangdise block has been uplifted discrepantly,along with the whole uplift of the Qinghai-Tibet Plateau since the Neogene.There exist many different kinds of nearly NS-trending fault structures along with the intense uplift of the plateau.In addition,the distribution and shapes of water systems and string-shaped lakes in Gangdise hinterland are controlled by the fierce neotectonic movement. |
