【摘要】：空間同位模式的局部挖掘算法存在挖掘結(jié)果無統(tǒng)計(jì)顯著性意義、缺少領(lǐng)域知識介入導(dǎo)致挖掘結(jié)果針對性不強(qiáng)等問題.通過引入領(lǐng)域?qū)＜抑R選擇候選模式,構(gòu)建候選模式屬性的興趣度函數(shù)作為局部空間統(tǒng)計(jì)量,對空間候選模式的興趣度值聚集區(qū)域進(jìn)行挖掘,進(jìn)而合并聚集區(qū)域的鄰域確定模式的空間區(qū)域.經(jīng)過分析及驗(yàn)證,利用該方法對長汀縣煙草種植適宜性結(jié)果數(shù)據(jù)集進(jìn)行處理,發(fā)現(xiàn)了主要養(yǎng)分高但不適合種植煙草的異常模式及區(qū)域.據(jù)此,專家有針對性地提出了加大灌溉基礎(chǔ)設(shè)施建設(shè)、施用石灰和硼肥等改善煙草種植條件的建議.
[Abstract]:The local mining algorithm of spatial colocation pattern has some problems such as no statistical significance of mining results and lack of domain knowledge intervention resulting in weak pertinence of mining results. By introducing domain expert knowledge to select candidate patterns, the interest function of candidate pattern attributes is constructed as local spatial statistics, and the interest value aggregation regions of spatial candidate patterns are mined. Then the spatial region of the neighborhood determination model of the aggregation region is merged. After analysis and verification, the data set of tobacco suitability in Changting County was processed, and the abnormal patterns and regions with high nutrient content but not suitable for tobacco planting were found. Accordingly, the experts put forward some suggestions to improve tobacco planting conditions, such as increasing irrigation infrastructure construction, applying lime and boron fertilizer and so on.
