| 摘 要： | 西藏墨脱县是迄今为止我国唯一不通公路的县。墨脱地处印度洋板块与欧亚板块的缝合带上 ,那里是地质灾害的博物馆。由于喜马拉雅山的阻隔以及交通、气候等条件的限制 ,无法采用常规手段进行公路的灾害地质勘察。为填补西藏墨脱地区地质资料的空白 ,作者采用了LandsatETM +、Ikonos- 2及航空遥感等多源遥感资料 ,并基于多层次地学遥感分析技术研究墨脱地区的地质灾害现象及其区域分布规律 ,准确地确定了路线通过的灾害地质体 ,为墨脱公路最佳路线方案的选择提供了技术手段和方法.

| Abstract: | Motuo County of Tibet is the only county without a highway in China. Motuo is located on the sewing-belt between the Indian Ocean block and the Europe-Asia block. It is the museum of geological hazards. Because of the constraint of the Himalayas, limited accessibility and the difficulty weather conditions, it is not practical to adopt the conventional ways in reconnaissance of the geological hazards along the potential route for the highway to be constructed. Hence the Landsat ETM+, Ikonos-2 and aero-photograph were adopted to fill up the gap of geological information in this area. The geological hazards and their distributions in the area were then characterized using multi-level geological remote sensing analysis, which provided guidelines in the identification of hazardous geological masses along the highway route. It proved to be a good method for the selection of the best route scheme of the Motuo road. |
