矿山环境侵蚀与堆积变化的3D-GIS分析——以大连市周边矿区为例

Study of 3D-GIS Visual Analysis for Mine Environment Based on Erosion and Accumulation by GIS:A Case in Urban Area of Dalian

本文利用3D-GIS的方法,结合遥感卫星数据,建立矿区时间序列的DEM模型,通过可视化技术,地形模型构建、矿山地貌特征分析、剖面分析、量化计算、侵蚀类型分析,研究了矿山环境的特点和主要问题。并以大连市区及周边区域作为研究区域,对1970年到2005年的侵蚀与堆积进行了计算,以及侵蚀的分类。结果表明,不同的侵蚀类型对矿山环境带来不同影响,因此,对矿山的整治应采取针对性的措施,才能达到防治保护的效果。试验认为,利用3D-GIS的可视化分析是进行矿山环境调查,制定矿山环境恢复治理措施的有效方法。

Using 3D-GIS and RS data,we created a time series DEM.Through 3D-GIS Visual Analysis,with efforts on landform character of mine sites,profile analysis,quantum calculation,classification for erosion types,characters of mine environment and problems were analyzed.Taking 1970 and 2005 DEM in Dalian as examples,we calculated erosion amounts and classified erosion types in the mine site.The result showed that different erosion types exert different effects.At the end of the paper,some measures for Dalian mine environment is put forward.Therefore,3D-GIS is an effective method for mine environmental investigation.
