| 摘 要： | 随着矿产资源的开发利用,形成了以矿区为中心的经济社区,但与此同时,由于开采技术水平低,管理者的环境意识淡薄,掠夺性开采造成了矿区环境的生态系统退化和破坏.基于地理信息系统对攀钢钒钛磁铁矿开采对周围环境影响,讨论了滑坡和泥石流对矿区周围环境的影响,以三维GIS的方法,构建了矿区的三维地形模型,通过三维模型分析可以很直观的求出滑坡和泥石流对矿区、居民区、水资源的影响,可以发现由于开采、尾矿堆放、矿坑排水的影响,不但可能会引发更多的泥石流、滑坡等地质灾害,而且对当地人民的生活产生较大的影响,利用GIS的强大建模和分析功能,为矿区开采及环境保护、合理利用矿产提供技术支持和决策依据.

| Abstract: | Low level of exploitation and weak awareness of environmental protection among administrators have caused degradation and destruction. This paper studies-the mineral environmental effect, discusses the impact of landslide and mudslide, and construct TIN model of mining area using 3D GIS method. Researches into the impact of landslide and mudslide over mining area, residential district and water resource detect that exploitation, gangue and draining will lead to more geological hazards and affect the living of the local people. The application of the strong fimction of modeling and analysis GIS will provide technological support for the exploitation and environmental protection and rational utilization of mineral products. |
