- Abstract:
- Spatial and temporal variations of soil water content was studied in different part of the sand dune-fixing and soil covered by different plant community in the Maowusu sandy land.The study shows that, water content in the soil is higher at the beginning of the growing season than that of at the end of the growing season.Temporal variations of soil water content in every plots can be portioned into three periods, they are the period of accumulation (April-June), consumption (July-September) and stabilization (October-next March), while the soil can be divided into four layers according to the spatial variations of water content: vertiginous layer, active layer, transitional layer and relative stable layer from the top to the bottom.The changing of the vertiginous layer was closely related to the distributing of the roots growing in the soil, deeper distributing of the roots leading to deeper vertiginous layer.Soil water content was variable in different part of the sand dune-fixing.The biggest water content was shown at the bottom of the slope, the next was shown at the middle and the smallest water content was shown at the top.
