利用GIS所提供的三维可视化功能,建立起矿山治理恢复后的具有真实感的三维景观模型,对评价规划方案、展示规划效果、通过三维可视化的形式反映矿山环境治理恢复前后的景观变化具有重要意义。ArcView 3D Analyst是ArcView GIS的扩充模块,...利用GIS所提供的三维可视化功能,建立起矿山治理恢复后的具有真实感的三维景观模型,对评价规划方案、展示规划效果、通过三维可视化的形式反映矿山环境治理恢复前后的景观变化具有重要意义。ArcView 3D Analyst是ArcView GIS的扩充模块,在ArcView 3D Analyst基础上建立了采空塌陷区的回填、削坡设计及其治理后矿山绿化等矿山治理恢复设计的三维景观模拟。展开更多
以湛江金沙湾海滩养护前后不同时期沉积物粒度监测数据、海底高程扫描数据和遥感影像为依据,运用Arc GIS 3D Analyst进行沉积物和海底地形分析,得出湛江市金沙湾海滩养护工程实施前后不同时期海底沉积物、地形表面和动态剖面变化情况。...以湛江金沙湾海滩养护前后不同时期沉积物粒度监测数据、海底高程扫描数据和遥感影像为依据,运用Arc GIS 3D Analyst进行沉积物和海底地形分析,得出湛江市金沙湾海滩养护工程实施前后不同时期海底沉积物、地形表面和动态剖面变化情况。结果表明,湛江金沙湾海滩侵蚀区域集中在风车广场对出海域和原红嘴鸥码头附近,后期应重点考虑对此区域进行修复重建。展开更多
