摘要:
土壤的水分含量、质地、均一性、温度等因素都会影响化学物质在土壤中的运移。在室内条件下，采用垂直土柱易混置换法，就不同质地及不同容重对Cl-在土壤中运移规律的影响进行了初步研究。研究结果表明：Cl-在黏粒含量高的土壤中的水动力弥散系数（D）大于在黏粒含量低的土壤中的水动力弥散系数，而延迟因子（R）则小于黏粒含量低的土壤。在同一质地不同容重条件下，D值随容重的下降而减小，R值则增大。
Abstract:
Chemicals’ transport in soils can be influenced by some soil factors,such as soil moisture, texture, homogeneity and soil temperature.The influence of the texture and the bulk density on chemicals’ transport under the laboratorial conditions are studied. The result is that the value of the hydraulic dispersion coefficient (D) in loessal soil is greater than that in aeolian sandy soil because of the relatively high content of clay compared with aeolian sandy soil, but the value of the retardation factor in loessal soil is smaller than that in aeolian sandy soil; and that the value of D become smaller and smaller with the bulk gravity decreasing and the value of R increased gradually.
