通过相关性数据处理和模糊聚类分析，对影响土壤环境腐蚀性的各种因素之间的相互关系进行了讨论．相关系数矩阵和聚类谱系图两者都表明，有些因素之间的相关性很大，有些相对独立．研究发现影响土壤环境腐蚀性的23项因素在相关系数大于0．8的情况下，可明显地聚为6类．这对石油沥青涂层管线土壤腐蚀性的深入研究，有一定的参考价值．
Through the correlation data processing and fuzzy clustering analysis, the relationship between the various factors that affect the corrosivity of soil environment is discussed. Both the correlation coefficient matrix and the cluster pedigree show that some factors are highly correlated and some are relatively independent. The study found that 23 factors that affect the corrosiveness of soil environment can be clearly grouped into six categories when the correlation coefficient is greater than 0.8. This petroleum asphalt coating pipeline soil corrosion in-depth study, have some reference value.
