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.
