Review on Sustainable Utilization of Salt-affected Land

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.
