DEM在矿区土地复垦中的应用研究

Application of DEM in Land Reclamation of Mining Area

土地复垦是保证矿区土地资源可持续利用的重要途径之一。但我国的土地复垦工作开展较晚,新技术和新理论研究较少,将DEM(D igital E levation Model)应用于矿区复垦土地中有助于提高决策水平。基于DEM应用于土地复垦,可以方便地分析复垦区土地资源的状况,为合理制定复垦方案提供技术支持。基于DEM建立起复垦后的具有真实感的三维景观模型,通过三维可视化的形式,反映土地复垦前后的景观变化,对评价规划方案、展示规划效果,提高各方面人士的参与复垦的积极性都有重要意义。

Land reclamation is one of the important ways to ensure a sustainable usage of the land resource in mining area. As land reclamation started late in China and little research has been done on related new technology and theory, the application of DEM （digital elevation models） will help to raise the decision -making level. Its application makes it convenient to analyze the conditions of the land resource in mining area so as to provide the technical support for making a rational land reclamation scheme. Three - dimensional model that has a sense of reality for the landseape after the reclamation can be built based on DEM. Through the 3D visualization mode, the change in the landscape before and after the land reclamation can be reflected, which will be of great significance to the assessment of the plan for land reclamation and the demonstration of the plan effect so as to increase the enthusiasm of the people of various circles for participation in land reclamation.
