| 中文摘要: |
| 琼海市处于华南褶皱系东部,人类工程活动强烈,地质灾害多发。文章采用信息量层次分析法,在琼海市1∶5万地质灾害详细调查的基础上,建立评价因子并转化成信息量值,接着由判断矩阵计算出被比较因子的权重值,最后利用ArcGIS的空间分析功能,以综合信息量值为依据,绘制琼海市地质灾害易发性分区图,为琼海市地质灾害防治提供依据。 |
| 英文摘要: |
| Qionghai City is located at the east part of the South China Fold System. There are lots of engineering activities in this area, and the geological hazards are often accompanied with these human activities. Analytical Hierarchy Process (AHP) for information is used in this article for the incidental geological hazard zoning in Qionghai City. Based on the results of 1:50000 geological hazard survey in Qionghai City, the assessment factors were transferred to values which were calculated by judgment matrix. The weighted values came from the results of judgment matrix were used by ArcGIS Spatial Analyst for mapping the incidental geological hazard zoning in Qionghai City,provide a basis of geological disaster prevention for Qionghai City. |
