在我国农业快速发展的大背景下,由于人类活动和自然条件的共同作用,我国盐碱地面积有不断扩大的趋势,对我国耕地红线构成严重威胁.目前,治理不同盐碱程度、不同类型盐碱地的措施逐渐多元化,总结过往的改良技术,分类分区,精准治理,兼顾高水平与低成本,对我国盐碱地治理具有重要的现实意义.本文就盐碱地的各项治理措施与研究进展进行了综述,并在此基础上对未来盐碱地治理研究方向进行了展望.
Under the background of the rapid development of agriculture,the area of saline-alkali land is constantly expanding due to the joint action of human activities and natural conditions,which is a serious threat to China′s arable land redline.At present,measures to improve different degrees and types of saline-alkali lands are gradually diversified.Summarizing past improvement techniques,classifying and zoning,precise improvement,and balancing high-level and low-cost have important practical significance for saline-alkali land improvement in China.This paper reviewed various improvement measures and research progress of saline-alkali land,and on this basis,prospected for future research directions in saline-alkali land improvement.
