澜沧江―湄公河地区地形地貌划分

Landform Division in Lancang-Mekong River Area

地形地貌反映了地质构造运动特征,是影响和制约区域经济社会发展的基础。本研究以澜沧江-湄公河地区1:250000TM遥感影像图为基础,考虑到本区新构造运动异常活跃以及微地貌的特殊性,结合其坡度形态及海拔高度,采用成因类型-成因形态-物质形态-坡度形态-微地貌形态的方法进行地貌类型划分研究。采用地势起伏度分级、野外查证等方法进一步验证了地貌划分成果,结果表明本次地形地貌划分研究较好地反映了客观实际。

Topography reflects the characteristics of the geological tectonic movement, which has influence and restriction on the basis of regional economic and social development. Based on the 1：250 000 TM remote sensing image data of the Lancang-Mekong area, the article makes a geomorphological classification research on the area. In the research the specially active new tectonic movement and characteristics of the microtopography, as well as the slope shape combined with the altitude, are considered, and a genetic type-causes form-physical form-slope form-microtopography form method is used to classify the landform types. Results from field survey have verified that the classification corresponds to the objective reality.
