摘　　要：以广西防城港市中心规划区为对象,利用该规划区地形图建立了数字高程模型(DEM),在此基础上叠加遥感影像与景观模型,形成了规划区虚拟三维环境,并对景观要素进行视域、地形、空间布局等相关分析,从而使城市景观规划设计建立在全面直观的空间模型之上,为制定合理的防城港规划区景观方案提供参考依据。The digital elevation model （DEM） was established through the topographic map of central planning area ot Fangchenggang City. On this basis, remote sensing images and landscape model were overlapped on DEM,which formed a virtual 3D environment. Simuhaneously, urban landscape planning design performed more intuitive attribute to the spatial model in terms of the analysis of viewshed, terrain, space layout, etc. of landscape elements. The results revealed that this paper provided an important reference for establishing reasonable landscape planning design for the city.
