摘　　要：本文利用ArcGIS软件的3D扩展模块ArcScene,以数字等高线生成格网DEM,转化为TIN后,通过遥感影像粘贴纹理,建立了环青海湖地区的三维景观模型.通过对研究区三维景观模型进行基本地形分析和水淹分析,提取了不同应用价值的地形要素信息,辅助完成了区域地貌划分与区域地貌识别,并有效模拟了未来青海湖水位上涨后对该区域的影响,直观演示了这种影响范围,为该地区生态环境变化研究及人类对这种变化的响应研究奠定了基础.The 3D Landscape model of Qinghai Lake area is established by using the 3D extended module ArcScene to generate the grid DEM from digital contour, transform from DEM to TIN and paste the texture of the remote sensing image. Through the basic terrain analysis and flooding analysis of the 3D landscape model, the terrain feature information of different application value is extracted, the regional geomorphology division and recognition are completed and the region effects of the future level rise of Qinghai Lake are effectively simulated and visually demonstrated. This paper provides the foundations in the study of the ecological enviromnent changes and the human response of the study area.
