基于不动点计算的岸线动态分析方法
A Dynamic Analysis Method of Coastline Based on the Computation of Stationary Points
-
摘要: 现有地理信息系统对于海岸线这一独特线对象的动态变化缺乏有效的管理和分析手段。针对该问题，该文引入不动点的概念，基于现有地理信息系统设计了一种基于不动点计算的岸线动态分析方法，达到分析海岸淤进或蚀退动态变化的目的，进而实现岸线动态变化的自动分析功能。文章对真实的黄河口岸线数据进行了实验分析，证明了基于不动点计算的岸线动态分析方法的有效性。

Abstract: Current GISs lack efficient management and analysis functions for coastline dynamic changes for coastline is a special line object. In order to resolve this problem, the concept of stationary points is introduced, and a coastline analysis method is put forward based on current GISs. Through analyzing stationary points, the dynamic changes of coastal siltation or erosion can be obtained. Thus, the analysis of coastline changes can be accomplished automatically. In this paper, experimental analysis is performed on the real coastline data of Yellow River Mouth, which turns out that this dynamic analysis method is valid. -
