模糊数学在土壤质量评价中的应用

利用FUZZY聚类分析方法,对黄土高原地区不同土属的土壤资源样品,按照其主要理化性状指标进行了分类;在此基础上,用二阶FUZZY综合评判方法对其质量优劣进行了评判排队(均通过微机进行计算处理),结果表明,模糊数学方法在土壤定量化研究中是一种较理想的新手段,基本切合土壤的实际,可为土壤资源的合理开发利用提供一定的科学依据.

APPLICATION OF FUZZY MATHEMATICS IN THE APPRAISAL OF SOIL QUALITY

Fuzzy clustering analysis is used to classify the different samples of the soil resources of the loess plateau, in accordance with their physicochemioal properties.On this basis, then, the samples are arranged in order of quality, using grade-2 Fuzzy synthetical judgement.It is shown that the Fuzzy approach in the quantitative research of soil, is far better than any other quantitative approach. It can provide a reliable soientifio basis for the protection and exploitation of soil resources. Therefore it is regarded as a basic approach to the appraisal of soil quality.
