摘要
Based on WorldView-2 high-resolution satellite image and ASTER GDEM(V1)digital elevation model (DEM)data,the authors studied geomorphological characteristics of the Tengchong volcanic region by means of remote-sensing interpretation,topography-elevation analysis,surficial-slope analysis and terrain-section analysis,with ArcGIS and Global Mapper. On the whole, the structure and evolution of the basin directly controlled and restricted the volcanic activities. At the meantime,the volcanic process transformed the geographic and geomorphic conditions of the basin and shaped the modern volcanic landscape features.
