地下水浅埋区盐碱地滴灌条件下土壤盐分运移研究

综述了国内外地下水浅埋条件下土壤盐分运移机理研究,滴灌条件下盐碱地土壤盐分运移机理研究,土壤盐分运移模型研究的相关研究成果,为滴灌技术在改造和利用地下水浅埋盐碱土地资源的应用提供了思路,为预报土壤盐碱化提供科学依据,并为地下水浅埋盐碱土滴灌条件下土壤盐分运移规律的进一步研究提出一些建议,认为地下水浅埋区盐碱地滴灌条件下土壤盐分运移规律的研究仍是今后土壤科学的研究重点.

Progress of the study on salt transport in saline soil under drip irrigation condition in shallow groundwater area

Under the decline salt water drip irrigation condition,the soil salt transport rule is the foundation for the utilization of land resources in shallow groundwater condition and prevention of soil salinification.The article summarized relevant research results at home and abroad about movement mechanism of soil salt in shallow groundwater,mechanism of salinification under drip irrigation and movement model of soil salt,developing new ideas of utilizing land resources of shallow groundwater under drip irrigation condition and putting forward some proposals for further study of soil salt transport rule under the salty water drip irrigation condition in shallow groundwater area.It is expected that research emphasis in future is the motion disciplinarian of soil salt under drip irrigation in shallow ground water saline area.
