盐碱地修复利用措施研究进展

研究盐碱地的生态修复对解决盐碱化土地有序利用、促进农牧业产业健康发展、遏制部分地区土壤盐渍化的加重与扩展等问题具有重要意义。笔者对近年来国内外盐碱地改良方法与技术的相关文献、报道进行整理,分析盐碱地修复利用研究所取得的成效与进展。盐碱地改良方式主要包括工程措施、化学措施、生物措施与综合措施。不同措施均在一定程度上取得了较好的盐碱地改良效果,将不同措施有机结合形成盐碱地修复利用集成技术体系并不断探索新的改良材料、改良技术,同时拉长对改良效果的评价与监测时限将成为今后盐碱地修复利用发展的方向。

Remediation Measures of Saline-alkali Land: A Review

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.
