Weighing method was adopted to study the formation time and the amount of soil condensation water in four habitats (mobile sandy land, fixed sandy land, farmland, and Mongolian pine forest land) in Horqin Sandy Land in August 2007. The soil condensation water began to form at 20:00-22:00, increased gradually at 22:00-4:00, and began to evaporate after 4:00. In the four habitats, soil condensation water was mainly formed in 0-9 cm layer, and the amount was the greatest in 0-3 cm layer, accounting for 40% of the total. The soil condensation water also formed in 9-30 cm layer, but in very small amount. There was a greater difference in the mean daily amount of soil condensation water in 0-3 cm layer in the four habitats, with the sequence of fixed sandy land > mobile sandy land > farmland > Mongolian pine forest land, which indicated that the habitat with better vegetation condition was not benefit the formation of soil condensation water. The mean daily amount of soil condensation water in 0-30 cm layer was 0.172 mm in fixed sandy land, 0.128 mm in Mongolian pine forest land, 0.120 mm in mobile sandy land, and 0.110 mm in farmland.
2007年8月，采用称重法对科尔沁沙地4种生境（流动沙地、固定沙地、农田和樟子松林）土壤凝结水的形成时间和凝结量进行了研究。土壤凝结水在20:00 - 22:00开始形成，22:00 - 4:00逐渐增加，4:00后开始蒸发。在这4种生境中，土壤凝结水主要在0 - 9 cm土层形成，其中0 - 3 cm土层凝结量最大，占总量的40%。9 - 30 cm土层也有土壤凝结水形成，但量极少。4种生境0 - 3 cm土层土壤凝结水平均日凝结量差异较大，顺序为固定沙地＞流动沙地＞农田＞樟子松林，这表明植被状况较好的生境不利于土壤凝结水的形成。固定沙地0 - 30 cm土层土壤凝结水平均日凝结量为0.172 mm，樟子松林为0.128 mm，流动沙地为0.120 mm，农田为0.110 mm。
