土壤水的研究,从Henri Darcy(1856)提出达西定律算起,已有一百多年历史.经历了由经验到理论、由静态到动态、由定性到定量、由宏观到微观逐步深入发展的过程.1877年Briggs L.J.提出毛管假说,将土壤孔隙组成的孔道看成是一些大小不同的毛细管,认为表面张力是土壤保持水分的主要原因.
The characteristics of moisture retention of main soils in Shanghai area have been studied by tension plate method (0-1 bars) and pressure membrane method (1-15 bars). Results showed that:In general, soil water suction was conversely correlated with soil water content. Under the low water suction, the soil water-holding capacity was dependent mainly on the content of organic matter, the adsorption of organic colloids and the influence of soil structure;while under the high water suction, it was closely related to the soil texture (i.e. the content of clay) and the molecular attractive force of specific surface area as well as the adsorption of organic colloids.
