摘要

文章在常规 TOPSIS(technique for order preference by similarity to ideal solution)模型的基础上提出空间 TOPSIS 模型, 以安徽省休宁县为例, 采用地理信息系统(geographic information system, GIS)技术对安徽省休宁县的滑坡易发性进行评价。研究表明: 基于 GIS 的空间 TOPSIS 模型的滑坡易发性评价, 能够处理和分析滑坡评价因子以及滑坡易发性的空间变化特征; 评价结果与休宁县境内已经发生滑坡的空间分布较为吻合, 评价结果较好。基于 GIS 的空间 TOPSIS 模型在滑坡易发性评价中具有较好的适用性。

Abstract

Based on the conventional technique for order preference by similarity to ideal solution (TOPSIS) model, this paper proposes a spatial TOPSIS model, and evaluates the landslide susceptibility in Xiuning County, Anhui Province using geographic information system (GIS). The results show that the landslide susceptibility assessment using GIS-based spatial TOPSIS model can process and analyze the spatial variation characteristics of landslide-affecting factors and landslide susceptibility. The resulted landslide susceptibility is in good agreement with the spatial distribution of landslides occurred in Xiuning County. The GIS-based spatial TOPSIS model has a good applicability in the assessment of landslide susceptibility.
