摘要
通过DEM、坡度及土地利用等地理信息的叠加,形象直观地反映出不同坡度条件下的土地利用情况,并且利用DEM的三维仿真模拟技术对土地利用信息进行三维可视化,从而为土地利用动态监测、分析与评价、决策与支持提供了技术保证,以便指导退耕还林、还牧、林果业的开发等工作。
The land-use situation on different grade is visually reflected by the overlap of geo-information on DEM,grade and land use.Furthermore,Land-use information is visualized by the technique of 3-D simulation based on DEM.Accordingly,it can give tech-guarantee for land-use dynamic monitoring,analysis and assessment,decision-making and supporting.Thus,it can be convenient to guide the work of reclaiming woodland and grazing land from arable land and exploitation of forestry and fruit.
