摘要

摘要: 当前对于涉及两个时期间海岸线蚀退型和淤积型区域的构建研究尚缺乏较为自动准确的方法。将两个时期的海岸线视为有向且无自相交的曲线，相互打断为若干有向折线段。通过总结各类型区域边界的构成规律，提出两时期海岸线间变迁区域的自动构建算法。构成变迁区域边界的海岸线折线段总是两个时期间隔出现，且有相同的起点或终点，移除构成某一变迁区域的所有折线段后，对其他区域的提取没有影响。据此规律，提取某一变迁区域边界上的所有折线段，利用其中的点构建区域，根据早期海岸线的方向，判断变迁区域的具体类型。以实际海岸线数据进行验证实验，结果符合预期。该算法可根据两个时期的海岸线，快速准确地提取出由水域变为陆地的淤积型区域和由陆地变为水域的蚀退型区域，为分析海岸线的时空变化特性提供辅助作用。

Abstract: There is important theoretical and practical significance to study the change of coastline. Currently, in order to complete coastline analysis work, it is short of the automatic and accurate algorithms which can construct and mark all the changed areas including erosional and increasing types between two period coastlines. We consider that all the coastlines distributed in the two periods have directions which are determined by the order of the points on the coastline, and don't intersect with themselves. Coastlines can only intersect with the ones in the other period which have different direction and will be cut into some polylines. By summarizing the distribution rules of polylines on the boundary of the changed area with different type, we get a number of conclusions and put forward the algorithm which can construct changed areas between two period coastlines automatically and mark them with different type exactly. The coastline polylines constituting edges of changed area always arise a period next to another which has the same start or end point. Removing all the polylines constituting a changed area, it will not affect the others. According to the rules, we can extract the polylines on a changed area's edge and build the area using the points. Judge the type of the changed area by examining the direction of earlier coastline which can be divided into clockwise or anticlockwise. We complete the programming of the function module. Several experiments are designed and implemented with some real coastline data collected in the actual projects. To test the algorithm is reliable or not, we compare the boundary and type of the changed area generated automatically by the algorithms with fact. And the results show that the method is effective and feasible. By our method, the erosional areas which changed into water from land and the accretion areas which changed into land from water can be constructed exactly and automatically according to two period coastlines. This provides assistances for spatial and temporal analysis of coastline change.
