针对滑坡地质灾害数据量大,数据结构复杂的特点,将GIS引入滑坡灾害危险性评价体系,主要利用到GIS强大的空间数据管理和分析能力。将GIS其作为滑坡灾害危险性评价的分析工具,来加速滑坡危险性的评价过程,提高危险性评价的精度。本文在工程实例的基础上,对基于GIS的滑坡灾害危险性评价体系进行全面的论述分析。
In view of the large data amount and complex data structure of landslide geological disasters, GIS is introduced into the landslide disaster risk assessment system, which mainly takes advantage of GIS’s powerful spatial data management and analysis capabilities. GIS as an analysis tool for landslide disaster risk assessment to speed up the process of landslide risk assessment and improve the accuracy of risk assessment. Based on the engineering examples, this paper makes a comprehensive discussion on the landslide disaster risk assessment system based on GIS.
