【摘要】：为科学分析滩涂资源特点及合理评价围垦利用适宜性,厘清滩涂土地利用分类管理及规划目标,基于MATLAB聚类统计工具,采用关联分析和系统模糊聚类结合方法对滩涂利用适宜性进行评价与分类。首先通过关联分析将各片滩涂的评价原始数据进行归一化处理后计算关联度集,并依据排序位次,确定各片滩涂围垦和农业利用可行性的重要程度进行排序。在关联分析基础上进行系统聚类,得到不同类别分类树结果,最终确定不同滩涂的适宜性评价的分类结果。盐城滩涂典型地区实例计算结果表明,垦区围垦适宜性评价指标达0.9,表明这些滩涂垦区最适宜进行围垦;盐城滩涂除少数垦区外,总体都可以进行农业开发适宜性利用。基于关联分析和系统聚类方法能够准确评价滩涂利用方式。
[Abstract]:In order to scientifically analyze the characteristics of tidal flat resources and evaluate the suitability of reclamation and utilization reasonably, and to clarify the classification management and planning objectives of land use in tidal flat, a statistical tool based on MATLAB clustering was used. Correlation analysis and systematic fuzzy clustering are used to evaluate and classify the suitability of beach use. Firstly, the correlation degree set is calculated by normalizing the evaluation data of each beach, and the importance degree of feasibility of reclamation and agricultural utilization of each beach is determined according to the ranking order. On the basis of correlation analysis, the classification results of different classification trees are obtained, and the classification results of suitability evaluation of different tidal flats are finally determined. The results of practical calculation in typical areas of Yancheng beach show that the evaluation index of reclamation suitability in reclamation area is up to 0.9, which indicates that these reclamation areas are the most suitable for reclamation, and Yancheng tidal flat, except for a few reclamation areas, can be used for agricultural exploitation in general. Based on correlation analysis and systematic clustering method, beach utilization can be evaluated accurately.
