摘要

本文介绍了基于GIS的地壳稳定性评价方法,选取了地震、构造、工程地质、地面沉降等4个因子,19个要素,提出了点、线、区图层定量处理方法,使用层次分析法确定权系数,通过GIS的叠加分析获得最终评价结果,以天津市为例给出了地壳稳定性评价图。
In this paper,the assessment method of crustal stability based on GIS technology is introduced. According to four selected factors such as earthquake,structure,engineering geology,surface subsidence,and 19 elements,we put forward to the treatment method about point-line-area graphic layers,and define the weight coefficients by the analytic hierarchy process.By the GIS overlap analysis,the final assessment result has been obtained.To take the Tianjin City as an example,the assessment map of crustal stability has been worked out.
