主成分分析法在港口岸线等级评价中的应用

岸线资源在经济发展中的地位越来越重要,岸线评价也成为岸线资源研究的重要工作.将主成分分析法引入岸线等级评价中,选定4个自然指标作为岸线等级评价的主要指标,利用MATLAB编程计算得出6条岸线的重要度,得分越大表明岸线的重要程度越高.最终将岸线划为3个等级,并将之应用到港口岸线规划中,对岸线的开发利用提出合理性建议.

Application of principal component analysis in waterline evaluation

The water-front resource is more and more important in the economic development.Waterline evaluation has also become an important task in water-front resource research field.We introduce the principal component analysis in waterline evaluation,selecting four main nature indices as the main indices of water-front level evaluation,and using MATLAB programming to obtain the importance of six waterlines.The higher the score is,the waterline is more important.In the end,three levels of the waterline are defined,which can be used in the plan of waterline.Reasonable advices for waterline development and utilization are put forward.
