高山峡谷地区的高精度地质灾害遥感解译方法研究

Study on the Method of High-precision Geological Hazard Remote Sensing Interpretation of Reservoir in the Mountain and Ravine Region

地质灾害调查是高山峡谷地区工程地质评价的重要基础和主要数据支撑,其传统方法需要大量的人力物力资源,通常会导致高成本。由于交通不便和复杂地理条件,有时很难或几乎不可能到达某些特殊位置开展工作。3S技术的发展和遥感解译分析方法,可以实现高精度地质灾害调查,并减少了大量的现场工作,真正实现了空间信息的三维可视化。

The geological disaster investigation on reservoir aea is one of the main tasks in engineering geological investigation of reservoir and is of an important basis and primary data of engineering geological evaluation. The traditional method of locating geological disaster needs a lot of manpower and resources , which will normally incur high cost . Also , sometimimpossible to have the research done at the field due to the inconvenient transportation and complex geographic condition. Meanwhile, the restriction of horizon makes it hard for geological engineers to get familiar with geological bodies inRS（remote sensing） application,GIS（ Geography Information System） techniques and 3D（three-dimensional） interpretation analysis method,high precision geological hazard investigation can be achieved with fewer field work if the spatial ization technology are used.
