高精度卫星遥感影像在景谷县地质环境调查中的应用

Application of High Precision Satellite Remote Sensing Image in Investigation of Geological Environment of Jinggu Autonomous County

选择SPOT-6卫星高精度遥感影像,以人类工程活动区域为解译范围,以RGB彩色合成图像作为解译的标准图像,经图像校正与增强、图像融合与图层叠加处理后,对景谷县自然地质环境、人类工程建筑等地理要素和滑坡、崩塌、泥石流等地质灾害进行了遥感解译。结果表明,景谷县3大地质灾害主要分布在河流两侧、山体陡峭区域,主要受植被破坏以及人类工程活动的影响。

Adopting SPOT-6 high precision satellite renlole sensing image, with human engineering activities region as interpretation range and RGB color composite image as standard image, through image correctiun and enhancement, image fusion and overlay processing, remote sensing interpretation was conducted on geographical factors such as natural geological environment, human engineering and construetion,geologieal disasters including landslide, collapse, debris flow in Jinggu Autonomous County. The results showed that three major geological disasters are mainly distributed in both sides of the river, mountain steep area, mainly due to the influence of vegetation destruction and human engineering activities.
