| 摘 要： | 运用统计软件SAS9．0，运用岭回归技术，对非充填复垦土壤的饱和导水率与土壤紧实度、土壤有机质含量、非毛管孔隙度、毛管孔隙度、容重、水稳性团聚体含量间的关系作了详细研究，并建立了饱和导水率的岭回归预测模型。结果表明，土壤饱和导水率与容重、紧实度、毛管孔隙度、非毛管孔隙度、有机质含量、水稳性团聚体含量之间存在着严重的多重共线性问题，各因子对饱和导水率的作用依次为非毛管孔隙度〉紧实度〉容重〉有机质含量〉毛管孔隙度〉水稳性团聚体含量。该模型对研究充填复垦土壤的饱和导水率具有重要意义。

| Abstract: | Using SAS9.0 software, the relationship between the soil saturated hydraulic conductivity and soil compaction,soil organic matter, non-capillary porosity, capillary porosity, bulk density and water-stable aggregate was studied applying ridge regression and a predicting model was established. The results showed that the multi-collincarity was serious between the soil saturated hydraulic conductivity and soil compaction,soil organic matter, non-capillary porosity, capillary porosity, bulk density and water-st... |
