| 摘 要： | 基于笔者在长江源区野外调查所取得的大量实际资料,结合前人研究成果,运用构造解析法,分析了长江源区新构造运动的特征,认为长江源区第四纪以来的构造运动十分强烈,新构造运动除以整体性、差异性和阶段性隆升的垂直运动外,还表现出以地壳缩短-推覆褶皱和断裂-块体走向滑动为主的水平运动,运动过程既表现出继承性复活,又有一定的改造性和新生性,新构造运动塑造了长江源区的地貌-水系格局。

| Abstract: | Based on numerous actual data collected from long-time field investigation in source region of the Yangtze River and refering to the former research achievement,we analyzed the neotectonics movement characters in source region of the Yangtze River using the structural analysis.The results show that the tectonic motion has been very intensive in source region of the Yangtze River since the Quaternary period.Except for the vertical movement with integrity,differences,and periodical uplift,the Neotectonics Mov... |
