Comparison of the Temporal Heterogeneity of Soil Moisture of Different Ecosystems at Red Soil Hillside Fields

Abstract:

This paper investigates the differences in the temporal heterogeneity of soil moisture between natural restoration ecosystem without disturbance (named as eco-1), restoration ecosystem with disturbance (named as eco-2) and shrubs ecosystem (named as eco-3) in red soil hillside fields. The probe soil moisture measured at 20 and 40 cm below the soil surface Hydrosense Portable Time Domain Reflectometry (TDR) system. The results showed that: (1) Daily measurements during a growing season showed significantly temporal interactions between vegetation and water. Soils under eco-2 (restoration ecosystem with disturbance) and eco-3 (shrubs ecosystem) were wettest at the start of the growing season but dries at the end; (2) The coefficient of variation of soil moisture content over time during the growing season was significantly higher in eco-2 than in eco-1, and at two depths beneath the soil surface (20 and 40 cm).
