摘　　要：开展"三江源"区域煤炭资源调查评价工作,对于保护当地生态环境和促进经济发展意义重大。以Landsat-TM数据为主要信息源,结合以往各类区域地质和煤田地质资料,对青海省乌丽-开心岭地区进行解译,确认该区为挤压性质背景下的北西西或近东西向构造特征的区域构造格架;探讨了区内构造演化和成煤古地理环境,以构造为重点,对基底构造、聚煤期构造以及聚煤期后构造对煤系聚集、赋存的影响进行分析,在此基础上圈定了晚二叠世含煤远景区3处,为下阶段煤炭资源勘探和开发提供了参考和指导。To carry on regional coal resources investigation and assessment in the ＂source of China＇s three major rivers＂ has great significance in the area＇s ecological environment protection and economic development promotion. Taking Landsat-TM data as the major information source, combined with a variety of past regional and coal geological data, integrally interpreted the Wuli-Kaixinling area, Qinghai, corffirmed the area＇s tectonic framework is NWW or near EW structural features under compression tectonic setting, discussed tectonic evolution and coal-forming paleogeographic environment. Based on tectonics, basement structure, coal-forming period, post coal-forming period structural impacts on coal measures accumulation and hosting have been analyzed. On these bases, circled out 3 Late Permian coal prospective areas, thus provide references and guidance for next stage coal resource exploration and exploitation.
