滇西北三江地区新构造运动特征

Moving Features of New Tectonic Movement in Three-river Area of Northwest Yunnan

滇西北三江地区新构造运动较为活跃和强烈,新构造运动主要表现为强烈的隆升运动.以地貌研究为主,从该地区多级阶地、多级夷平面的发育、河流袭夺等方面归纳了新构造运动的表现特征,简要总结出新构造运动的特点及其与环境的关系.

The new tectonic movement in the three-river area of northwest Yunnan is active and intense, which mainly shows the movement of swelling. Based on the research of landform, this paper concludes the features of new tectonic movement from the respects of growing up of multilevel land and multilevel smoothness, and attack by rivers in this area, and summarizes the features of new tectonic movement and its relationship with environment briefly.
