摘要
矿山泥石流是个突出的环境问题,采用RS与GIS技术研究其形成条件具有宏观、准确、快速的优点。在矿山泥石流评价、预测模型中,地形地貌、物源和植被覆盖是矿山泥石流形成的内在条件和基础,降雨是矿山泥石流爆发的主要动力和激发因素。现以太原市虎峪沟流域为例,运用RS与GIS技术定量研究矿山泥石流形成条件,包括:地形地貌、植被覆盖、泥石流物源、降雨等。运用RS技术解译泥石流物源分布、土地利用、植被覆盖情况;采用GIS手段提取流域地形地貌信息;以对矿山泥石流危险性评价、等级划分、预测预警提供数据支持。
Mudslide in mine is a prominent environmental issue. RS and GIS are macroscopic, accurate, and rapid in the study of formation condition of the mudslide. In the evaluation model and prediction model for the mudslide in mines, topography, source, and vegetation cover are internal conditions and foundations for its formation. Besides, precipitation is a major motive factor. Taking Huyugou Basin in Taiyuan as an example, RS and GIS are used in quantitative study on the mudslide formation conditions, including: topography, vegetation cover, source of mudslide, precipitation, etc. While RS technology is used to explain the situations including the source distribution, land utilization, and vegetation cover, GIS is used to find topography information. The study could provide data for hazard assessment, grading, and forecasting and warning for the mudslide in mines.
