盐碱地可持续利用研究综述

Review on Sustainable Utilization of Salt-affected Land

盐碱地资源的开发利用对粮食生产具有重大贡献。但水资源的缺乏、气候变化使盐碱地开发利用工作更具挑战性。文章系统总结了近年来盐碱地可持续利用研究取得的重要进展:(1)盐碱地可持续利用的技术研发、排盐水环境安全处理及技术配套管理研究;(2)盐碱地可持续利用的农户技术选择行为研究;(3)盐碱地可持续利用的科学研究方法。提出盐碱地可持续利用进一步研究的建议:加强多学科交叉融合的研究;强调农户技术选择行为研究;增强研究方法的科学性。

The exploitation of salt-affected land resources has made significant contribution to grain production. However it will be faced with a big challenge due to fresh water shortage and climate change. In the past few years, great progress has been made in sustainable utilization of salt-affected land. The contents of this paper include the following parts： （1） the major progress of Technology Research and Development （Tech RD）, drainage waters disposed off in an environmentally safe manner, and necessary management for technology of sustainable use of salt-affected land; （2） a detailed review of farm household behavior of technology choice for sustainable salt-affected land; （3） a brief review of the scientific research method for sustainable use of saline land. It is suggested that the following aspects should be further studied： （1） to strengthen the cooperation of scientists in different disciplines; （2） to emphasize the research on micro-subject farm household behavior of technology choice; （3） to increase the scientificity of research method.
