| 摘 要： | 以甘肃省秦安县果园石灰性土壤为研究对象,采用水平土柱入渗法,探讨了不同矿化度下(lg/L、3g/L、5g/L、10g/L)的三种钠盐(Nacl、Na2SO4和Na2CO3)对石灰性土壤水分扩散率的影响.结果表明:在水盐复合迁移体系中盐分与水分迁移具有不同步性,影响不同步性的因子与盐分类型有很大关系.NaCl对水分移动速... |

| Abstract: | The unsaturated soil moisture diffusivity is one of the important parametres of studying soil water and salt movement.At present,a few researches have been given more attention to the influence of soil water movement on salt transfer in water and salt complex system,but the study on the constraint relationship of salt transfer to water movement was deficient.Because soil moisture movement parameters were influenced by many factors and the process of soil formation,such as soil texture,soil structure,the con... |
