【摘要】：為科學分析灘涂資源特點及合理評價圍墾利用適宜性,厘清灘涂土地利用分類管理及規(guī)劃目標,基于MATLAB聚類統(tǒng)計工具,采用關聯(lián)分析和系統(tǒng)模糊聚類結(jié)合方法對灘涂利用適宜性進行評價與分類。首先通過關聯(lián)分析將各片灘涂的評價原始數(shù)據(jù)進行歸一化處理后計算關聯(lián)度集,并依據(jù)排序位次,確定各片灘涂圍墾和農(nóng)業(yè)利用可行性的重要程度進行排序。在關聯(lián)分析基礎上進行系統(tǒng)聚類,得到不同類別分類樹結(jié)果,最終確定不同灘涂的適宜性評價的分類結(jié)果。鹽城灘涂典型地區(qū)實例計算結(jié)果表明,墾區(qū)圍墾適宜性評價指標達0.9,表明這些灘涂墾區(qū)最適宜進行圍墾;鹽城灘涂除少數(shù)墾區(qū)外,總體都可以進行農(nóng)業(yè)開發(fā)適宜性利用�；陉P聯(lián)分析和系統(tǒng)聚類方法能夠準確評價灘涂利用方式。
[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.
