摘要:
将熵值理论与模糊物元建模相结合,应用于水土保持耕作模式评价中,建立了基于熵权的模糊物元模型。引用信息熵所反映数据本身的效用值来计算指标的权重系数,有效地避免了权重分配困难的问题和主观确定权重的人为干扰。该模型以一种新的方法进行水土保持耕作模式评价,能避免单个指标值进行比较而出现的偏离,并结合实例进行应用,体现了该模型的合理、简便和实用。
Abstract:
The method which combine the entropy value theory with fuzzy matter-element modeling was applied in soil and water conservation tillage technology model evaluation,and an entropy fuzzy matter-element model was established.It can avoid the problem of weight allocation effectively that using the utility value which reflected the date themselves by information entropy.The new way evaluating the sloping farmland soil and water conservation technologies can avoid the deviation resulted from the comparison between the single indexes.It was indicated that the method is reasonable and useful through an example analysis.
