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。
