松嫩平原盐碱地改良治理研究进展

Research progress on saline-alkali land improvement in Songnen Plain

松嫩平原是我国北方重要的农牧业基地,其西部是我国盐碱地主要分布区之一,属于典型内陆苏打盐碱地类型。由于土壤中含有大量可溶性盐,导致土壤理化性质恶化,抑制植物生长发育,严重影响农业生态环境和生产效益,有必要进行治理改良。盐碱地作为最重要的后备耕地资源,在转化为农业用地过程中具有潜力大的独特优势。采用物理、化学、水利工程和生物措施等针对盐碱地进行治理,可以将盐碱地转换为农业用地,由此扩大农业用地资源,从而保障国家粮食安全,改善区域农业生态环境。本文通过综述松嫩平原西部地区盐碱地治理研究,为我国盐碱地综合治理提供理论依据和决策参考,对于改善盐碱地区域生态环境,促进区域农业经济、社会和生态的绿色可持续发展具有重要意义。

The Songnen Plain is an important agricultural and animal husbandry base in North China,and its western part is one of the main distribution areas of saline-alkali land in China,which is a typical inland soda saline type.Due to the large amount of soluble salts in the soil,it leads to the deterioration of soil physical and chemical properties,inhibits plant growth and development,seriously affects the agroecological environment and production efficiency.Thus,it is essential to manage and improve the saline-alkaline soil.As the most important reserve arable land resource,saline-alkali land has the unique advantage of high potential in the process of conversion into agricultural land.By using physical,chemical,hydraulic engineering and biological measures to treat saline-alkali land,the land can be converted into agricultural land,thus expanding agricultural land resources,consequently guaranteeing the national food security,and improving the regional agroecological environment.This paper provides a theoretical basis and decision reference for the comprehensive management of saline-alkali land in China by reviewing the research on saline-alkali land management in the western region of the Songnen Plain,which is important for improving the regional ecological environment of saline-alkali land and promoting the green and sustainable development of regional agricultural economy,society and ecology.
