| 摘 要： | 经济的快速发展使人类活动导致的地质灾害问题越来越严重,建设项目是目前人类活动的一项重要内容,国家已明确要求对建设项目进行地质灾害危险性评估。针对目前建设项目地质灾害危险性评估大多处于定性评估阶段的现状,提出利用GIS技术进行建设项目危险性评估。以桂西某县冶金化工加工厂建设项目为例,设计了基于GIS的地质危险性评估模型,详细介绍了评估过程,并通过GIS技术实现了评估结果的可视化显示。实践证明,GIS技术可为建设项目地质灾害危险性的定量评估和可视化输出提供科学的表现方法。 |

| Abstract: | The fast economical development causes the geological disaster problem which the humanity activity causes to be more and more serious, construction project is an important content of humanity activities, our country has definitely requested to carry on the geological disaster risk appraisal for construction project. In view of the present situation that geology disaster risk appraisal of construction project mostly is at the qualitative evaluation stage, this paper proposes to carry on construction project risk evaluation using GIS. Take a county metallurgy chemical industry processing factory in western Guangxi as the example, the paper designes geological risk evaluation model based on GIS, introduces in detail the appraisal process, and demonstrates visually the appraisal result by GIS. The practice proves that GIS may provide the scientific performance method for construction project geologic hazard risk quantitative assessment and visualization output. |
