| Abstract: | In this study, the physical properties of soil moisture and soil water retention were measured in plots of 20 m×30 m in the mingled forest of Pinus tabulaeformis Carr. and Robinia pseudoacacia L., pure forests of P. tabulaeformis Carr. and R. pseudoacacia L., and non forest land in Beipiao County of Liaoning Province. The results showed that the soil physical properties including soil porosity, soil mechanical composition, soil water retention, soil permeability and soil water storage capacity in the mingled forest of P. tabulaeformis Carr. and R. pseudoacacia L. were all better than those in the pure forests and non forest land. All the values of soil in the pure forests of P. tabulaeformis Carr. and R. pseudoacacia L. were similar. The comprehensive evaluation revealed that soil water retention in the mingled forest of P. tabulaeformis Carr. and R. pseudoacacia L. was the highest among the three forest types. The linear regression equations of the main factors affecting the saturated hydraulic conductivity (EMAS) were developed. |
