陆海统筹地形地貌综合编图方法研究

Comprehensive mapping technology of integrated land and sea topography and geomorphy

由于陆海地形数据在调查程度和精度上存在较大差距,地形图件陆海联编较为困难。系统梳理了海岸带地形地貌陆海统筹的复杂程度,总结了陆海联编地形图的基本原则,探讨不同情况下陆海地形数据的无缝拼接方法和图件编制的主要要素。以南通陆海统筹地形地貌综合图为例,按照成果类型综合归类,进行地形、地貌、坡度、冲淤变化等信息的综合集成,绘制陆海统筹的地形地貌综合成果图,通过1张图即可查询。陆海统筹地形地貌综合成果新的展现形式,有利于成果的查询和实际应用,供后期开展相应的陆海图件联编参考。

Due to the big gap between the accuracy and the degree of geological survey of land and sea topography,it is difficult to draw a topographical map of both areas. This paper systematically reviews the difficulty of data integration on coastal zones,summarized the basic principles of comprehensive mapping land and sea topography,and discussed the seamless splicing method and the main elements of map compilation under different circumstances. Taking the comprehensive mapping of land and sea topography and geomorphology of Nantong as an example,this paper classified the results and carried out the comprehensive integration of terrain,landform,slope,scour and silting change,which came out as a map of land-sea integrated topographic and geomorphic results. It is beneficial to promote the real application of the results,and provide reference for the corresponding land and sea map compilation in the future.
