摘要:

地质灾害危险性评价是近年来地质灾害领域一个快速发展的交叉学科,经过多年的发展形成了一套较为完整的理论体系,但学者在实践应用中仍会遇到或忽视个别问题。本文对区域地质灾害危险性评估流程进行归纳,将评估流程分为评价单元选择、评估指标体系构建、评估模型与方法分析、危险性评价、评估结果有效性论证方法和危险性区划和应用等六方面内容。对各个部分的关键问题可选择性进行了分析,总结了现阶段各步骤各选择的适宜性,实现了基于GIS的区域地质灾害危险性评价流程体系构建。

Abstract:

As a fast developmental interdiscipline of geological disasters,geohazard assessment has formed a relatively complete theoretical system in recent years.However,scholars and engineers are still confused by some problems in practical application or tend to ignore some specific problems.After a summarised work on regional geohazard assessment,the process of geohazard assessment are divided into six categories in this paper,including assessment unit selection,evaluation index system construction,analysis of assess model and method,geological disaster hazard assessment,effectiveness evaluation methods of assessment result and zoning map.The selectivity of key issues concerning each part is analyzed and the suitability of various choices at each step in the current phase is summarized.Finally,the regional geological hazard risk assessment system is constructed on the basis of GIS,which has a certain indication significance for fundamental research.
