Study of Soil Saturated Hydraulic Conductivity in Sand Dunes of the Horqin Sand Land
Water is a limiting factor to plant growth in the Horqin Sand Land of China. Knowledge of soil saturated hydraulic conductivity (Kfs) is of importance because Kfs influences soil evaporation and water cycling under natural/artificial conditions at various scales. Kfs at fixed dunes and shifting dunes of the Horqin Sand Land were measured in situ by the Gueph permeameter. The results indicated that (1) Kfs ranged from 0.48 to 10.25 mm/min, and showed that Kfs of fixed dunes is bigger than it at shifting dunes; (2) Kfs at fixed dunes increased with increasing soil depths, but for shifting dunes, it diminished with increasing soil depths; (3) Kfs at fixed dunes is significant negative correlation with hardness, while it significant negative correlation with hardness and organic matter content at shifting dunes.
