| 摘 要： | 在污水灌溉区和清水灌溉区不同点及深度上取样分析，测定土壤在污灌前后的土壤含水率、有效孔晾率和非饱和导水率的特征变化．研究结果表明：土壤在污染后其水分渗透特征发生变化，土壤含水率增高，有效孔隙率和非饱和导水率下降．土壤表观含水率变化由其渗透特征参数变化引起． |
| 关 键 词： | 污灌 土壤渗透特征 含水率 有效孔隙率 非饱和导水率 |

| Abstract: | The soil samples were acquired from polluted fields and unpolluted fields respectively.Water content,effective porosity and unsaturated hydraulic conductivity of samples were measured.The results showed that soil permeability characteristics were changed after pollution,and soil water content increased but effective porosity,unsaturated hydraulic conductivity of soil decrease.The change of soil water content resulted from change in soil permeability index. |
| Keywords: | sewage irrigation soil permeability character soil water content effective porosity unsaturated hydraulic conductivity |
