摘　　要：渔场地貌是分析预报渔情、选择渔业作业方式和选用渔具设备的重要依据之一。基于数字高程模型(DEM)和数字晕渲制图等技术,应用ESRI Arc GIS软件系统,通过实验方法选定DEM插值算法及阴影光源参数,制作了表现海底地形起伏变化特征及鱼类生物资源分布状况的渔场地貌图,实现了多源、多维和异构数据的融合。作为一项探索性工作,期望设计成果能够为今后相关产品的研发和应用提供有益借鉴。Landform of fishing ground is an important reference in analyzing fishery forecast and selecting fishery operation methods and fishing gears. In this paper,based on the techniques of digital elevation modeling（ DEM）,digital relief shading and ESRI Arc GIS software,the DEMinterpolation algorithm and shadowlight source parameters are selecteal by experimental methods. Marine fishery geomorphic map is created,which can vividly describe the fluctuation of seafloor topography and fish biology resources distribution,to achieve a fusion of multi-source,multi-dimensional and heterogeneous data. As an exploring program,the study results are expected to provide valuable reference for the development and application of related products in the future.
