soil organic carbon (g kg -1 ), BD: bulk density (g cm -3 ). 52 Fig. 4.1. Demonstration of sample grids in the experimental site (example for UG 79). Each site has an area of 105 m×135 m. Sampling points are spaced every 15 m with a subgrid spacing of 5 m (Hollow circles donate the field long-term monitoring positions). 69 Fig. 4.2. Ranked MRD of soil moisture in UG 79 in different water conditions during 3-yr measurement period (All: all measurements, D: dry, M: medium, W: wet). Vertical bars correspond to associated time standard deviations, labeled numbers are the time stability points that at least appear three times from four soil water conditions. 73 Fig. 4.3. Ranked MRD of soil moisture in UG 99 in different water conditions during 3-yr measurement period (All: all measurements, D: dry, M: medium, W: wet). Vertical bars correspond to associated time standard deviations, labeled numbers are the time stability points that at least appear three times from four soil water conditions. 73 Fig. 4.4. Ranked MRD of soil moisture in WG in different water conditions during 3-yr measurement period (All: all conditions, D: dry, M: medium, W: wet). Vertical bars correspond to associated time standard deviations, labeled numbers are the time stability points that at least appear three times from four soil water conditions. 74 Fig. 4.5. Ranked MRD of soil moisture in HG in different water conditions during 3-yr measurement period (All: all measurements, D: dry, M: medium, W: wet). Vertical bars correspond to associated time standard deviations, labeled numbers are the time stability points that at least appear three times from four soil water conditions. 74 Fig. 4.6. Distribution of drier points than overall average moisture content in WG <strong>und</strong>er different water conditions during 3-yr measurement period (All: all measurements, D: dry, M: medium, W: wet; labeled numbers are the points that soil moisture drier than field average moisture content). 75 Fig. 4.7. Field mean soil moisture versus soil moisture of time stable point in four sites during the period of 2004-2006 (a:UG 79; b: UG 99; c: WG; and d: HG). 77 Fig. 4.8. Cumulative infiltration and fitting curve for the p72 location in UG 79. 80 Fig. 4.9. Soil moisture comparison between measured and simulated results in UG 79 during the growing period in 2006 (Measured: measured value in field long-term monitoring site; Modelled: modelled result based HYDRUS-1D; TSP: xii
measured soil moisture in time stability point). 81 Fig. 5.1. Pore size distribution for the four grazing intensities in four soil depths. Sparse: large pore size (>50 μm), pF
