【摘要】 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．更多还原

【Abstract】 By considering the data correlation and using the fuzzy cluster of pattern recognition,the relationship among varions corrosive factors of soil was investigated. Both the matrix of correlation coefficients and the pedigree of factor clusters show that some factors are correlated closely to each other, while others are relatively independent. The correlation coefficients are very high between the parameters such as organic substances and total nitrides, organic substances and microorganism total salts and conductivity, density and void volume etc. However, the CO2-3, sulfur oxide bacterias etc., indicate much lower correlation coefficients with soil pH. And the 23 soil corrosive factors are clusterd into 6 distinct clusters under the correlation coefficien value above 0.8. The results of will be helpful to the further study on the soil corrosivity of petroleum asphalt coated pipe.更多还原
