| Abstract: |
| In order to reveal the characteristics of spatial distribution of soil moisture in the close planting Jujube forest in Northern Shaanxi Province, continuous monitoring of soil moisture in 0~200 cm soil layer was carried out in different positions(inter-trce, inter-row and center-point) of the Jujube forest. The results indicated that soil moisture of inter-tree was significantly better than inter-row in July~September. The average soil water of inter-tree, inter-row and center-point was 9.77%, 7.66% and 7.52%. With the changing of rainfall, cumulative infiltration was different in various positions of the Jujube forest. The infiltration capacity of inter-tree was larger than that of inter-row. With the in-crease of rainfall, the infiltration capacity increased in all positions and the infiltration was recharged. The function in in-ter-tree increased, but that in inter-row decreased. For example, in the moderate rain(p=14.8 mm), the infiltration capacity of inter-tree, inter-row and center-point was 15.5 mm, 8.8mm and 8.4 mm; while in the heavy rain(p=31.6 mm), that was 30.9mm, 16.5mm and 12.8 mm,
respectively. The average daily consumption of soil water in
inter-tree was the highest(4.09 mm/d), followed by that in inter-row(3.77 mm/d), and that in center-point was the lowest(2.77 mm/d) in all positions. |
