摘　　要：文中概述了青藏高原基本构造格局、青藏高原多岛弧盆系统洋陆转换演化模式。然后,结合1∶25万西藏邦多、措麦区幅区调工作中地质构造单元及演化阶段划分,蛇绿混杂岩带野外调查等实际问题进行了初步探讨,并提出建议。This paper has dealt briefly with the basic structural framework,and the marine-land transfer and evolutional model of the archipelago arc-basin system of the Qinghai-Tibet plateau.Based on1:250000region-al geological survey in the Bangduo and Cuomai map sheet areas in Tibet Autonomous Region,a discuss has been made on the identification of tectonic elements and the reconstruction of their evolutional history,the work-ing method in the investigation of ophiolitic melange in the field,and other practical problems,on which some suggestions have finally been made.
