Soil water dynamics of Pinus sylvestris var. mongolica plantations on sandy lands in Zhanggutai areas

Located research on soil water dynamics of Pinus sylvestris var. mongolica plantations on sandy lands and moving dunes in Zhanggutai areas were carried out. The results indicated that: in the whole growth season, the influence of such factors as rainfall, evaporation and radiation and soil texture on soil water was significant. Soil water storage of 0～100 cm layer was highest for plantations at the foot of sand hills, and followed by moving dunes, which for plantations at hilltops was lowest. Soil water contents of surface soil were influenced by rainfall remarkably, plantations was higher that moving dunes; soil water contents in major rooting layers 25～50 cm of Pinus sylvestris var. mongolica were lower than moving dunes. Losses of moisture in the soil were in May, June and September, storages of moisture in the soil were in July and August, soil water storage was lowest in June.
