摘要
土壤体系本身非常复杂 ,其腐蚀性的影响因素很多 ,如何合理有效地评价土壤腐蚀性是金属防腐设计的基础 .基于模糊物元理论 ,提出了土壤腐蚀性评价的新方法 .其关键在于 :①确定土壤理化指标隶属度的类型及大小 ;②计算各指标的权重与关联系数 ;③构成关联度复合模糊物元 .该方法评价结果不仅可以反映土壤腐蚀性的强弱 ,而且可以反映各因素对土壤腐蚀性的影响程度 ,其应用充分说明了该方法的有效性和合理性 。
Soil system itself is very complex,and there are many factors effecting on its corrosivity.How to evaluate soil corrosivity reasonably and effectively is the basis of preventing metal materials against corrosion.Based on fuzzy matter-element theory,a new method for soil corrosivity to be evaluated is proposed.Its key is to determine the type and quantity of membership grades of each physical and chemical index,calculate its weights and relational coefficients and compose the composite fuzzy matter element of relational grades.The evaluation results of this method can show not only the extent of soil corrosivity,but also the influencing extent of each factor on soil corrosivity.It's application fully shows the effectiveness and rationality of this method,which provides an effective means for soil corrosivity evaluation.
