地理信息系统支持下的滑坡灾害分析模型研究

STUDY ON GIS-AIDED MODEL FOR ANALYSIS OF LANDSLIDE HAZARD

运用GIS等技术手段 ,集成相关模型对滑坡变形失稳危险性进行分析是一个重要研究内容。进行有效的滑坡灾害分析的关键是采取适当的分析模型及模型单元。通过对已有的基于GIS的分析模型的综合论述 ,对各种分析模型及模型单元的特点及其局限性进行了详细分析 ,并取得一些重要认识。

The integration of GIS and corresponding models plays more and more important role in analysis of landslide hazard. To select proper model and its elements is a key issue for landslide hazard analysis. After an integrated discussion of GIS-aided model for analysis current landslide hazard, the characteristics of each model and their elements and their limitations are studied in detail. Then some important conclusions are made.
