摘要
针对我国西北地区土壤剖面多呈层状结构和土壤的盐渍化面积逐年增加的实际情况,概述了国内外入渗和蒸发条件下非均质层状土壤水盐运移的研究动态,总结了其主要研究成果,明晰了成果之间的相互关系及其实际应用价值,探讨了研究中目前存在的主要问题,为灌溉和排水等措施的拟定以及进一步的研究提供参考信息。
Considering the fact that most soil profile assumes layered structure in the field and soil secondary salinity area gradually increases in northwest China, the transport features of water and salt in layered soil under infiltration and evaporation are reviewed based on the research results at home and abroad, the achievement obtained and theirs interrelationship are clarified, and the problem existed is presented and discussed. The paper may provide some information for further studies on transport of water and solute in layered soil and for the design of irrigation and drainage scheme.
