摘要
土地盐渍化已经成为全球性问题,并严重影响了我国的生态环境,因此,改良并利用盐渍化土地对我国生态环境修复具有重要意义。徐圩新区作为国家重点示范区,应急水源地建设是新区建设的重要一环。调查表明,徐圩新区应急水源地面临着水质污染和土地盐渍化两大问题。本工程采用“前置预处理、中端功能湿地及后置生态调蓄库”的组合工艺,通过模块化处理流程,结合湿地生态系统净化功能,提升水源水质和降低盐度;通过多种措施达到盐碱地改良和水质净化的目的,探究盐碱地生态治理策略。
Land salinization has become a global problem and has seriously affected China s ecological environment.Therefore,improving and utilizing salinized land is of great significance for China s ecological environment restoration.As a national key demonstration area.The construction of emergency water source is an important part of the construction of Xuwei New Area.The investigation shows that the emergency water source area of Xuwei New Area is faced with two major problems:water pollution and land salinization.This project adopts the combined process of“pre-pretreatment,mid-functional wetland and post-ecological regulation and storage”,and improves the water quality through the modular treatment process and the purification function of wetland ecosystem.Through a variety of measures to achieve the purpose of saline-alkali land improvement and water purification,to explore the saline-alkali land ecological management strategies.
