| 摘 要： | 岫岩县是辽宁省东部山地地质灾害最为典型的地区，存在以崩塌、滑坡、泥石流为主的多种地质灾害。本文应用大量野外地质灾害调查所收集的各种资料，建立Access数据库，并在GIS软件平台上运用投影转换功能，将数据库文件转换为具有属性的图形文件，并得到地质灾害分布图；将研究区进行网格剖分后，对已矢量化的各图层及灾害点文件叠加运算，得到灾害易发程度分区图、等值线图。分区的结果揭示了地质灾害空间分布特征及其与地质环境和人类活动的关系。 |

| Abstract: | Xiuyan County is a typical area hit by geological hazards of mountains in eastern Liaoning. These hazards mainly include collapses, landslides and mud-debris flow. On the basis of a wealth of data gathered in field investigations of geological hazards, an access database was established. By using the function of projection change on the platform of the GIS software, the files of the database were transformed into graphic files with an attribute and the distribution map of geological hazards was also constructed. Through the superposed calculation on the vectored layers and the files of hazard points after the research area was gridded, the regionalization map and isoline map of hazard-prone degrees were prepared. The hazard regionalization reveals the spatial distribution of geological hazards and their relations with the geological environment and human activities. |
