摘要
针对盐渍土分类中客观存在的模糊性与随机性,将信息论中的熵值理论引入盐渍土综合评价中,运用信息熵所反映数据本身的效用值计算盐渍土评价中各指标的权值,使得权值的分配有了一定的理论依据,并结合传统的模糊综合评判法对盐渍土做出评价。工程实例表明:模糊综合评判法用于盐渍土评价是合理可行的。
Because of the uncertainty of indexes in the process of classifying solonchak soil, the entropy value theory is applied to combining the traditional fuzzy comprehensive evaluation method for salt-affected soil classification. The coefficients of weight for evaluation factors are obtained from the available value of data reflecting the information entropy, by which the weight allocation is more reasonable. This method is applied to salt-affected soil classification. And the calculated result compared with attribute recognition method indicated that the proposed method is reasonable and practical.
