| 摘 要： | 对风蚀沙化过渡地带沙地凝结水进行了研究，结果表明，该地区沙地凝结水主要发生在0～15cm土层内；表层凝结水量较少，基本上作为无效水分而蒸发，15cm的凝结水量相对较大，若15cm的凝结水量长期维持在此水平，则对于浅根性植物的生长极为有利。

| Abstract: | To research condensation water of sands in interim region of deflation and desertification, draw a conclusion that condensation water occurs to in depth of 0-15 cm in region. Condensation water is less on soil surface, and evaporated as invalid one. But condensation water is still more in depth of 15 cm, if the moisture storage capacity maintains the level for a long time, it is vital for growth of shallow rooted plant. |

| Keywords: | condensation water interim region of deflation and desertification temporal and spatial variation |
