| 摘 要： | 基于Landsat8 OLI数据,针对长白山地区综合使用比值法和主成分分析法提取水热蚀变信息,提取精度经野外验证为83.3%。利用等距分区加权叠加分析的统计方法对该地区水热蚀变分布和主要断裂带的空间关系进行了定量分析。研究结果表明水热蚀变的强度与该区域距断裂带的距离呈现负相关。新形成的断裂带附近以及断裂带的交汇处水热蚀变强度较大。

| Abstract: | The Landsat 8 OLI data was used to extract hydrothermal alteration information of Changbai Mountain area by the ratio method and principal component analysis method. The extraction precision verified by the field investigation was 83.3%. Isometric partitioned weighted superposition analysis of statistical methods was used to achieve the quantitative analysis of the spatial relations between the distribution of hydrothermal alteration and the main fault zone. The results show a negative correlation between the intensity of the hydrothermal alteration and the distance from the fault, and the high intensity hydrothermal alteration occurred near the newly formed fault and intersecting zone of faults. |
