【摘要】：為科學(xué)分析灘涂資源特點(diǎn)及合理評(píng)價(jià)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(biāo),基于MATLAB聚類統(tǒng)計(jì)工具,采用關(guān)聯(lián)分析和系統(tǒng)模糊聚類結(jié)合方法對(duì)灘涂利用適宜性進(jìn)行評(píng)價(jià)與分類。首先通過(guò)關(guān)聯(lián)分析將各片灘涂的評(píng)價(jià)原始數(shù)據(jù)進(jìn)行歸一化處理后計(jì)算關(guān)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(jìn)行排序。在關(guān)聯(lián)分析基礎(chǔ)上進(jìn)行系統(tǒng)聚類,得到不同類別分類樹(shù)結(jié)果,最終確定不同灘涂的適宜性評(píng)價(jià)的分類結(jié)果。鹽城灘涂典型地區(qū)實(shí)例計(jì)算結(jié)果表明,墾區(qū)圍墾適宜性評(píng)價(jià)指標(biāo)達(dá)0.9,表明這些灘涂墾區(qū)最適宜進(jìn)行圍墾;鹽城灘涂除少數(shù)墾區(qū)外,總體都可以進(jìn)行農(nóng)業(yè)開(kāi)發(fā)適宜性利用�；陉P(guān)聯(lián)分析和系統(tǒng)聚類方法能夠準(zhǔn)確評(píng)價(jià)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.
