摘要
研究了评价方法在土壤肥力中的应用,提出了基于粗糙集的土壤肥力组合评价方法。针对北京市褐潮土长期定位实验数据,使用主成分分析法、灰色关联法和模糊综合评价法等3种方法进行单一评价,评价结果把土壤分为极高、高、中、低、极低等5个等级,最后使用粗糙集组合评价方法,克服了单一方法的非一致性,得到了较好的实验结果。
This paper studies the application of evaluation method on soil fertility and proposes a novel technique： combination evaluation method-based on rough set applied on soil fertility evaluation.Based on aqui-cinnamon in Beijing long-term stationary experiment data,the experiment first uses principal components analysis,grey relational and fuzzy comprehensive assessment to get single evaluation,and then uses combination evaluation based on rough set to evaluate.Compared with these three methods,combination evaluation based on rough set gets a better performance.
