基于VRMap的矿区土地资源破坏三维可视化与分析模型集成系统

A system integrated with three-dimensional visualization and analytical model of mine area land resource destruction based on VRMap

矿产开发导致的土地资源被破坏,既是环境污染与矿区地质灾害形成的源头,也使得土地供需的矛盾日趋尖锐,成了威胁"矿群"关系和谐及矿区可持续利用发展的中心问题。基于VRMap建立了以遥感、汇水、坡度作为背景纹理的矿区开采面、固态废物、尾矿库、工矿道路和工矿建筑5类土地破坏的三维模型,集成土地利用变化模型,以三维量算面积为模型参数,基于VRMap SDK开发模型分析三维地理信息集成系统,为矿区土地破坏的直观显示、深刻理解与全面分析提供技术支持。

Land resource destruction due to mineral resource development not only aggravates the contradiction of land supply and demand,but also is the origin of mine area geological hazard and environmental pollution. It has becomes the core problem that influences the sustainable development of mining area and harms the relationship of the mining groups. This paper established a three-dimensional data model of land destruction of mining surface, solid waste,tailing reservoir,industrial mining road and industrial and mining construction based on VRMap and remote sensing,slope and watershed image as background texture,built up the land destruction dynamic change analytical model based on land use change measure model and three-dimensional measurement area,and developed a system integrated with three-dimensional visualization and analytical model based on VRMap SDK. These work could provide technical support for visually displaying,synthetically analyzing and deeply understanding the mine land resource destruction.
