摘要
分析了海岸工程规划中传统的水下地形冲淤计算方法的不足，介绍了地理信息系统（ＧＩＳ）的基本组成及其在水下地形冲淤计算中的应用实例．在浙江舟山渔港港域地形冲淤变化分析中，利用ＧＩＳ工具软件ＡＲＣ／ＩＮＦＯ分别建立了该水域１９６２年、１９８７年和１９９６年三个不同时期的数字高程模型（ＤＥＭ），计算了１９６２～１９８７年和１９８７～１９９６年两个时段的冲淤深度与相应的冲淤面积和冲淤量，为建港环境条件分析提供了依据．
This paper analyzes the disadvantages of conventional way of calculating the subwater topography change in coastal engineering planning,introduces the main components of Geographic Information System (GIS) and gives an example of application of GIS in subwater topography calculation.In the analysis of subwater topography change in the area of Zhoushan Fishery Harbour in Zhejiang Province,three Digital Elevation Models (DEMs) of the area under study for 1962,1987 and 1996 are developed respectively using GIS software ARC/INFO,and the change of depth and the corresponding change of area and volume are calculated for the periods from 1962 to 1987 and from 1987 to 1996,providing a solid basis for the environmental analysis of the fishery harbour.
