| 摘 要： | 土壤肥力受到自然因素和人为因素的双重影响,而且评价指标数据集较大属于高维数据,因此对其进行客观的综合评价显得非常困难。运用属性识别理论模型和层次分析法对土壤肥力综合评价进行了研究,结果与模糊综合评价模型的评价结果相一致。运用层次分析法确定评价指标权重系数,避免了权重确定的主观性,同时该模型计算简单,适应于有评价标准的质量评价问题。表3,参12。

| Abstract: | Soil fertility is affected by both nature factors and artificial factors which are in large and high dimensional data.It is difficult to evaluate it externally.This paper used Attribute Recognition Theoretical Model and analytic hierarchy process to evaluate soil fertility,and the result is consistent with that of fuzzy comprehensive evaluation model.It avoided subjectivity of confirming weights by using analytic hierarchy process to ascertain evaluation indexes' weight coefficients.This model is simple to compute and apt to evaluate quality issues that have evaluation criteria. |
