摘要
为了全面、科学地优选坡耕地水土保持牧草,提出了熵权系数法,介绍了该法的基本原理,建立了综合考虑多种因素的牧草优选的熵权系数法模型,并用实例加以说明,所得结果与灰色关联评价结果一致,说明该方法用于坡耕地水土保持牧草优选是有效的,在系统工程中具有广泛的应用价值。
In order to optimizing the grassess of sloping field for soil and water conservation, entropy coefficient was applied and its basic theory was introduced. Meanwhile some factors are taken account. It was explained by an example, the result is similar to that of the grey relation method, so this method can be used to choose the water- saving irrigation scheme.
