摘要
通过遥感图像的目视解译及人机交互解译来识别地质灾害体,并在GIS系统支持下参考区域地质、地貌背景,对地质灾害发育规律和分布特征作进一步分析。可大大提高工作效率和成果的准确性,对于区域性地质灾害(尤其是崩塌、滑坡和泥石流)的调查目前是最为有效的方法。这个方法为地质灾害的地学分析提供了一个直观的工作平台,对于发现其各种地学规律,提高研究程度帮助极大。
Based on visual interpretation and human-computer-interaction interpretation in identifying the geological hazards, further studies in terms of development laws and distribution characteristic have been carried out referring to regional geology and topographic setting by the GIS system. That may greatly enhance working efficiency and result accuracy as a mostly valid way at present during the survey of regional geological hazards, especially such as slumping, landslide and mudflow. This way supplies a visual platform for catastrophic analyses in geoscience and is considerably available to discovery multiform geoscience laws and improves studying levels.
