补充资料：土壤水
| 土壤水 soil water 包气带土壤孔隙中存在的和土壤颗粒吸附的水分。通常有下列4种形式：①吸附在土壤颗粒表面的吸着水。又称强结合水。土壤颗粒对它的吸力很大，离颗粒表面很近的水分子，排列十分紧密，受到的吸引力相当于10000个大气压。这一层水溶解盐类能力弱，－78℃时仍不冻结，具有固态水性质，不能流动，但可转化为气态水而移动。②在吸着水外表形成的薄膜水。又称弱结合水。土粒对它的吸引力减弱，受吸力为31～6.25大气压 ，与液态水性质相似，能从薄膜较厚处向较薄处移动。③依靠毛细管的吸引力被保持在土壤孔隙中的毛细管水 。所受的吸力为6.25～0.08大气压。毛细管水可传递静水压力，被植物根系全部吸收。④受重力作用而移动的重力水，具一般液态水的性质。除上层滞水外不易保持在土壤上层。土壤水的增长、消退和动态变化与降水、蒸发、散发和径流有密切关系。
