    摘要:

    草地土壤次生盐渍化是松嫩平原次生盐碱斑形成的主要原因。草地土壤次生盐渍化是在该地区气候干旱、地下水位较高等潜在盐渍化因素的基础上,由于人为因素干扰强度不断增大,草地植被遭到严重破坏而诱发的土壤次生盐渍化过程。草地次生盐渍土具有其独特的剖面形态和理化性质。防治草地土壤次生盐渍化的有效途径是保护和恢复植被。

    Abstract:

    The secondary salinization of grassland soil is the mam reason for the formation of secondary saline-alkaline soil pathes in grasslands in Songnen Plain.Inthe presence of potential salinization factors such as dry climate and high underground water level the secondary salinization of grassland soil was induced because vegetation had been ruined due to strong anthropogenic interference.Therefore,the secondary saline-alkaline soil in grassland had its special profile and physical and chemical characterstics.It is suggested that to protect and recover vegetation is an effective way to prevent and improve secondary saline-alkaline grassland soil in Songnen Plain.
