摘　　要：基于云南中甸地区ETM影像数据,借助ENVI软件进行了蚀变异常信息提取,采用线、环构造频度图统计方法来定量研究工作区线、环构造与矿化蚀变信息之间的空间配置关系。结果显示,线、环构造交点高频度区和线、环交点高频度区,与蚀变信息分布最多的区域相关性良好。蚀变信息空间分布位置与大型构造位置大致吻合,分布总体趋势依附线、环性构造走势。This article selected the ETM image data in Zhongdian Area of Yunnan,and extracted mineralization alteration information with the help of ENVI software.The figure line and the ring structure frequency methods were used to quantitatively study the spatial configuration of relationship between mineralization alteration information and structure of line,and ring in workspace.The results show that the high frequency of line and ring structure node and high frequency of line ring node area have a good regional correlation with most alteration information distribution.The spatial distribution of alteration information and the large tectonic location is roughly consistent,and the overall alteration information distribution depended on the line and ring tectonic movements in this study area.
