基于信息熵理论的灰色系统法在岸线评价中的应用

选定岸线前沿水深条件、岸线稳定性、岸线前沿水域宽度以及岸线后方陆域宽度作为岸线评价的主要指标。在确定评价指标的权重时应用了信息熵理论,随后将灰色系统法引入到岸线评价中,利用MATLAB编程计算得出6条岸线的关联度,关联度越大表明岸线与最优岸线越相关,最终得出各岸线与最优岸线的相关性排序,并对评价结果进行了对比分析,对岸线的开发利用提出合理性建议。

Application of entropy-based grey system theory in shoreline evaluation

Four main nature indexes are selected as main indexes of water-front evaluation,including the forefront of water deep,the stability of shoreline,the width of water area and the width of land.This paper involves information entropy theory to confirm the rate of indexes,and involves grey system theory in shoreline evaluation.Then the correlation degree of six shorelines are calculated by using MATLAB programming.The greater the correlation degree is,the more relevant the shorelines are.In the end,the order of correlation concerned about each shoreline with optimal shoreline is obtained.The reasonable suggestion for shoreline exploitation is put forward.
