“三北”地区盐碱地治理技术研究进展

Research Progress of Saline-alkali Soil Treatment Technology in Three-north Areas

盐碱地是我国重要的后备耕地资源。我国盐碱地面积巨大、分布广泛,盐渍化耕地超过20%。盐碱地的开发和治理,尤其"三北"地区对提高粮食产量和改善生态环境具有极其重要的意义。本文对近60年"三北"地区盐碱地治理技术的研究进行综述,提出盐碱地治理的策略和途径,为未来盐碱地改良技术的开发提供参考价值。

Saline-alkali land is an important arable land sources in China,which is large and widespread.Salinization of arable land has account for 20% of the whole arable land.The exploitation and improvement of saline-alkali land is an important role for increasing the grain yield and improving ecological environment,particularly in the Three-north areas.In this paper,the research of saline-alkali land treatment technology in Threenorth areas in recent 60 years was reviewed,and put forward some strategies for improving technology of the saline-alkali soil and to provide basis for future saline-alkali improvement.
