摘　　要：通过资料收集及野外地质调查,滇西高黎贡山南段新构造表现,可归纳为断陷盆地沿断裂串珠状分布;剥蚀夷平面、河流阶地发育;断块差异运动显著;河流水系错断现象普遍;新生代地层分布广且厚度差异大;地势反差大;新生代地层发生褶皱、断裂;地热活动强烈,沿活动断裂带温泉出露较多;地震活动频繁;岩浆活动频繁,火山火山活动强烈;地质灾害发育;部分地段地下水放射性元素含量较高等12种特征,这些新构造运动表现都有着独特的遥感影像特征。According to the data collection and field geological survey,the neotectonic appearances include the following 12 characteristics,such as the string distribution along fault of fault downthrow basin,disintegration planation surface,river terrace development,clear differential movement of fault block,popular dislocation of river system,wide distribution and very different thickness of Cenozoic strata,very contrastive landform,intense fold,fault and geothermal activity of Cenozoic strata,many hot spring outcropped along active fault zone,frequent earthquake and magmatism,intense volcanism,geological disaster development,radioactive element content high of underground water in local area,etc.which have distinct remote sensing image feature.
