中文摘要：

针对土壤次生盐渍化问题，本文在分析土壤中盐分运移机理的基础上，结合“七场-相变-扩散模型”，建立了土壤盐分方程。设计了室内环境风洞土柱实验，对水盐运动规律进行了研究。从而为下一步的研究工作打下了基础。

英文摘要：

To deal with the problem of soil secondary salinization, the mechanism of salt transfer in soil was studied, the soil salt equation was established on the basis of ＂seven field-evaporation- diffusion＂ model; and the indoor soil column experiment was designed as well in the environmental wind tunnel, so the transfer rule of water and salt could be studied. It provides a fundamental study for further research work.
