Multi-scale prediction model and transformation relation of soil saturated hydraulic conductivity

  • n this study, the relationships between soil saturated hydraulic conductivity and physical properties in different soil layers was examined with joint multifractal method, multi-scale prediction model of soil saturated hydraulic conductivity with above conclusions educed was established, and transformation relation of soil saturated hydraulic conductivity between different soil layers was constructed. The results showed that sorting of correlation degree between soil saturated hydraulic conductivity and physical properties in different soil layers was different; at single scale and multi-scale, sorting of correlation degree between soil saturated hydraulic conductivity and physical properties in 0-20 cm soil layer was same, and one in 20-40 cm soil layer was different; developed multi-scale prediction models of soil saturated hydraulic conductivity had high precision, and root mean square error of fitted soil saturated hydraulic conductivity in 0-20 cm and 20-40 cm soil layers was 0.035 0 and 0.029 0, respectively; precision of transformation relation of soil saturated hydraulic conductivity between 0-20 cm and 20-40 cm soil layers was high, and root mean square error of fitted soil saturated hydraulic conductivity was 0.037 5.
