摘　　要：溶质在土壤中的运移受土壤结构、质地、水分含量、地被植物等因素的影响。在室内条件下,采用恒定水头法研究亮蓝在鹫峰地区土壤中的运移规律,得到同一样地不同深度下的亮蓝穿透曲线。研究结果表明:在鹫峰地区,溶质在土壤中存在明显的优先运移现象,土壤容重、孔隙度和饱和导水率均能影响溶质在土壤中的运移。Soil solute transport in soils can be influenced by some soil factors, such as structure, texture and moisture content of soil and ground cover plants. Using the constant-hydraulic head method to study the transporting laws of brilliant blue in soil from Jiufeng district under laboratorial conditions, and the breakthrough curves of brilliant blue in soil at different depths in the same plots were obtained. The results showed that there were obvious priority transport phenomena of solute in soil in Jiufeng district and it was affected by soil bulk density, porosity and saturated hydraulic conductivity.
