海岸带地区陆海图的差异分析

Analysis of Differences Between Topographic Map and Chart in Coastal Zone

海岸带是影响人类活动的重要地带。随着海洋经济的发展,海岸带专题图的需求日益增加。详细介绍了目前海岸带地区地形图和海图表示方法的各种差异,分析了产生这些差异的根本原因;阐述了消除地形图和海图差异的办法即新建海岸带地形图,编制海岸带地形图测量和编绘规范,编制海岸带地形图图式,统一海岸带地形要素的表示内容和表示方法。在此基础上根据不同的需要测绘海岸带地形图,为经济建设和社会发展提供有力的技术支持。

The coastal zone was one of the most important zones which influences on the human. With the development of ocean economy and the increasing needs for military activities, the requirement of the thematic map of coastal zone was on the increase. In this paper, the differences in representation between topographic map and chart in coastal zone at present were described in detail, The basic reasons for these differences were analyzed, the method to eliminate the differences between topographic map and chart in coastal zone were stated, which was to create a new kind of coastal topographic map, to constitute the specification for surveying and mapping of the coastal topographic map, to constitute the pattern of the coastal topographic map, to union the representation of contents and means of terrain elements in coastal zone. Afterwards, we will survey the coastal topographic map for the purpose of our needs, thus these maps will provide an effective technical support for preparing for military affairs, building economy and improving society.
