Abstract:

The research on ecological remediation of saline-alkali land is of great significance to saline-alkali land orderly utilization, the healthy development of agriculture and animal husbandry industry, and curbing the aggravation and expansion of soil salinization in some areas. This paper summarizes the literatures and reports on saline-alkali land improvement methods and technologies at home and abroad in recent years, analyzes the achievements of the research on saline-alkali land restoration and utilization. So far saline-alkali land improvement mainly includes engineering measures, chemical measures, biological measures and comprehensive measures. The application of different measures has achieved preferable results. To consolidate different measures to form the integrated saline-alkali land restoration technology system, constantly explore new materials and technologies, and extend the time line of evaluation and monitoring on the improvement effect will be the development direction of saline and alkali land restoration and utilization in the future.

Key words: saline-alkali land, saline-alkali land remediation, engineering measures, chemical measures, biological measures
