摘要
The effects of the root system of trees, shrubs and grasses on the hydraulic andphysical properties of soil and their interrelation with increasing soil anti--scouribility byroots are quantitatively demonstrated in this paper for the first time. Based on the analysisof the leading factors of roots to increase the soil anti--scouribility, a mathematical modelon increasing soil anti-scouribility by roots is established. The value in application of themodel is to explain the mechanism of roots to increase the soil anti-scouribility and toevaluate the increasing effects of soil anti-scouribility by roots in different layers of soilThe calculated results of the values in soil anti--scouribility intensified by roots at variousintensities of rainfall and slopes of the model have higher precision, all of the meanmaximum deviations between the estimated and observed values being less than 1.417 s/g.
The effects of the root system of trees, shrubs and grasses on the hydraulic and
physical properties of soil and their interrelation with increasing soil anti--scouribility by
roots are quantitatively demonstrated in this paper for the first time. Based on the analysis
of the leading factors of roots to increase the soil anti--scouribility, a mathematical model
on increasing soil anti-scouribility by roots is established. The value in application of the
model is to explain the mechanism of roots to increase the soil anti-scouribility and to
evaluate the increasing effects of soil anti-scouribility by roots in different layers of soil
The calculated results of the values in soil anti--scouribility intensified by roots at various
intensities of rainfall and slopes of the model have higher precision, all of the mean
maximum deviations between the estimated and observed values being less than 1.417 s/g.
