摘要

摘要本文介绍了GIS-MCA-AHP综合模型在越南丹阳地区滑坡易感性评价中的应用结果。主要的研究方法是基于层次分析过程和GIS空间分析模型相结合的多准则评价。研究结果表明，引起滑坡的因素主要有水文地质因素、地形地貌因素、地表覆盖因素和人为影响因素四大类。通过滑坡易感性评价图，确定了22.69%的区域(204.96 km2)为滑坡高危区和极高危区。基于重叠人口分布图和滑坡易感性评价图。有证据表明，包括723户家庭在内的居民区需要转移到安全地区，这些家庭位于山体滑坡的高风险地区。这对于预警和减少越南山区山体滑坡的风险是一个非常重要的研究方向。

Landslide susceptibility assessment for warning of dangerous areas in Tan Uyen district, Lai Chau province, Vietnam

ABSTRACT This paper presents the results of applying GIS–MCA–AHP integrated model in landslide susceptibility assessment for warning of dangerous areas in the Tan Uyen district of Vietnam. The main research method is a Multi-criteria assessment that is based on a hierarchical analysis process and a combination of the GIS spatial analysis model. Research results have shown four main groups of factors causing landslides including hydrogeological factors, topographic and geomorphological factors, surface cover factors and human impact factors. The landslide susceptibility assessment map has identified 22.69% of the area (204.96 km2) with a high and very high risk of landslides. Based on the overlapping population distribution map and landslide susceptibility assessment map. It has been shown that residential areas, including 723 households located at a high risk of landslides need to be moved to a safe area. This is a very significant research direction in a warning and minimizing the risk of landslides in mountainous areas of Vietnam.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
