摘　　要：研究区地处我国西南热带雨林区,气候湿润多雨,土壤植被较发育、基岩出露少,给遥感地质解译带来了很大困难。为最大限度地降低热带雨林覆盖区所带来干扰因素的影响,采用高空间分辨率遥感数据、雷达遥感数据和高程数据等,在常规遥感地质解译方法的基础上,利用植被和土壤与下伏基岩的关联性、地形地貌与地质体的关联性和人类工程活动与岩性的关联性,总结出研究区内各地质体在色调、形态、地貌和人类工程活动等方面的解译标志,开展了热带雨林覆盖区遥感地质解译和地质填图,并取得了较好的成效,可为类似区域地质调查提供较可靠的遥感地质解译方法参考。The research area is located in the tropical rainforest region in Southwest China,with a humid and rainy climate,and there are many soils and vegetation in this area and few exposed rocks.These factors have brought great difficulties to remote sensing mapping.In order to minimize the impact oFdisturbances caused by tropical rainforest coverage areas,the authors used high spatial resolution remote sensing data,Radar remote sensing data,and elevation data.On the basis of conventional remote sensing geological interpretation methods,the authors used the correlation between vegetation and underlying bedrock,soil and underlying bedrock,topography and geological bodies,human engineering activities and lithology to summarize the interpreting marks of various geological bodies in this region such as hue,morphology,geomorphology,and human engineering activities and develop remote sensing geological interpretation and geological mapping of tropical rainforest coverage areas,thus achieving good results and providing relatively reliable remote sensing geological interpretation methods for similar regional geological surveys.
