摘要
Abstract
In the period of 1989-1995, observations were carried out in the unsaturated zone above the depth of 4m in a field of water balance with lysimeters in Urab, Xinjiang. Results show that the amount of condensed recharge was significantly depended on the specific surface of media and hydraulic "conductivity: cobble mixed with gravel in 2. 58mm/a, gravel in 3. 15mm/a, middle sand in 9. 90mm/a, fine sand in 35. 87mm/a, and silt in 10. 04mm/a. The extrapolation volume of condensed water for silty sand and cohesive soil were 20mm/ a and less than 10mm/a, the maximum volume was estimated as much as 50mm/a in media. The best period for condensed water formation in the unsaturated zone in an arid desert was from April to September. The account of groundwater resources is more than 3×1010m3/A in volume in northwest China, which maybe greater than the infiltration of precipitation. Thus the condensed water formed in the unsaturated zone can be the crucial recharge resources in certain arid areas. The observed data with the lysimeter are also analyzed in detail in this article.关键词
