摘要
GIS技术以其强大的空间数据管理能力和空间分析能力受到广大地学工作者的青睐。作者在充分掌握岷江上游环境背景资料和泥石流分布资料的基础上，在泥石流危险度区划的理论指导下，将GIS技术应用于该区的泥石流危险度区划，得到了可信度较高的区划结果。GIS技术的应用，给泥石流危险度区划带来了手段上的革新。
Regionalization of danger degree is a comprehensive research on the debris flow problem. A case study using GIS technology is carried out in the upper reaches of Minjiang River,which is one of the heaviest disaster regions of debris flow. We use ARC/INFO to overlay different thematic maps into one comprehensive map, a mathematic model is built ac-cording to the AHP. Thus we can class the danger degree and get the division maps.
