摘　　要：通山县地形地貌复杂,地理场景的三维可视化能服务于野外地质实习,帮助学生在室内对陌生的野外实习点地形地貌特征建立感性认识,明确实习任务和面临的各种风险,具有较强的现实意义。本文基于通山县的卫星遥感影像及数字高程模型,利用GIS三维建模技术建立了一个通山县地质实习区域的三维地理场景模型,服务于地质实习教学。对其中的个别细节地理要素进行分析识别,既实现了对实习区域地理现象的再现,又能让学生在实习前先进行预习,对实习区域有个基本认识以提高野外实习的效率。The terrain of Tongshan county is complex,and the three-dimensional visualization of geographical scenes can serve the field geology practice,help students to establish a perceptual understanding of the terrain and geomorphology features of the unfamiliar field practice points in the indoor environment,and clarify the internship tasks and various risks,which has a strong practical significance.Based on the satellite remote sensing image and digital elevation model of Tongshan county,this paper establishes a three-dimensional geographical scene model of Tongshan county geological practice area by using GIS 3D modeling technology,which serves the geological practice teaching.The analysis and identification of individual details of the geographical elements,all these works not only realize the fidelity of the geographical phenomenon in the internship area,but also enable students to preview before the internship,so as to have a basic understanding of the internship area to improve theefficiency of the field internship.
