| 4. | The relationship of soil particle - size distributions and soil water retention characteristics , saturated and unsaturated hydraulic conductivity were studied in the lab 本研究对陕西四种不同质地土壤的粒径分布与水分特征曲线及饱和、非饱和导水率的关系进行了研究。 |
| 5. | 5 . to describe soil water movement with fractal model . the effect of soil pore radius and pore connectivity on soil water movement was studied . in addition of pore connectivity , the prediction of unsaturated hydraulic conductivity is more improved in low water content 将新的土壤结构分形维数应用于对土壤水分运动参数的描述,使饱和导水率和非饱和导水率预测的准确性有了很大程度地提高。 |
| 6. | The change of big pore section shape has more influence on soil water movement , but in small pore channels , the influence is small , in addition of pore section shape , it can get better prediction of unsaturated hydraulic conductivity 粗大孔隙通道的截面形状及变化对水分运动影响较大,较细空隙通道截面的形状对水分运动影响较小。修正孔隙截面形状对水分运动的影响,进一步考虑孔隙截面形状因子对土壤水分运动的影响,可以得到对土壤水分运动参数更正确地预测。 |
