摘要
运用多元回归分析方法,探讨黄褐土土壤阳离子交换量(CEC)与影响因子之间的关系。结果表明,土壤CEC与黏粒、pH之间存在正相关关系,而与砂粒、粉粒之间则存在显著的负相关。其中与黏粒的相关系数最大,pH次之。
The influencing factors in CEC of yellow-cinnamon soil were studied with multiple regression analysis pH, and was the methods. The results showed that CEC of the soil displayed significant positive correlations with clay, significant negative correlation with sand and silt. The correlation coefficient between CEC and clay biggest, followed by pH.
