多元联系数集对分析模型在土壤肥力综合评价中的应用

Application of Set Pair Analysis Model with Multi-Element Connection Number in Soil Fertility Evaluation

建立了利用多元联系数集对分析方法进行土壤肥力综合评价的新模型,并通过实例研究了评价效果,取得了满意的结果。与属性识别评价法和模糊综合评价法相比,该评价模型严谨,评价结果合理、精细、分辨率高,可为土壤肥力综合评价提供一种简单而适用的评价方法。

A new model for soil fertility evaluation was established by using the set pair analysis method with multi-element connection number.An applied example was studied with more satisfactory results.Compared with the attribute recognition theoretical evaluation method and fuzzy comprehensive evaluation model,this model is perfect.The evaluating result is more reasonable and its resolving power is higher.Thus,a simple and effective evaluation method is provided for soil fertility evaluation.
