摘　　要：罗平地区地质构造背景复杂,对该区构造格架的研究有利于揭示弥勒—师宗断裂北缘的构造演化。本文利用遥感技术可以宏观上对断裂特征进行全面解译和识别的特点,结合野外调查,分析提取断裂的影像特征,在对断裂构造进行密度分析的基础上,详细分析了断裂在地质地貌上的特征。研究发现,罗平地区北东向断裂带是师宗—弥勒断裂北沿部分,对罗平地区三叠系以来的地层沉积和构造演化有着直接的控制作用,形成了断裂两侧不同的地貌特征。In view of the complex structure background in Luoping area,the authors studied the tectonic framework of this area,with the purpose of revealing the tectonic evolution in the northern part of the Mile-Shizong fault.The characteristics of remote sensing technology were used to interpret and identify the faults macroscopically.Through field survey,the image features of the faults were acquired.On the basis of the density analysis of the faults,the detailed fault characteristics were studied from the viewpoint of geological and topographic features.The results show that the NE-trending fault belt in Luoping is the northern extension of the Mile-Shizong fault.This belt has controlled sedimentary and tectonic evolution since the Triassic in Luoping,with the development of different features on the two sides of the fault belt.
