干旱区区域土壤盐渍化监测研究进展及其未来热点

土壤盐渍化是干旱区农业生产的重要障碍，威胁着绿洲生态环境的稳定。监测土壤盐渍化动态，掌握盐渍化土壤的分布规律，探索盐渍化的发生发展机理，总结土壤盐渍化的研究方法，对干旱区农业生产活动和生态安全稳定具有重要意义。盐渍化的发展变化不仅受到自然环境的强烈作用，同时也受到人类活动的深刻影响。随着人类活动的加剧，盐渍化问题日益突出，因此本文在中外关于土壤盐渍化研究的基础上，系统总结了我国干旱区区域土壤盐渍化监测的主要方法，为土壤盐渍化监测、预报和调控的方法与理论提供了补充，同时也提出了当前干旱区区域土壤盐渍化监测研究存在的问题，以及强调了今后面向区域农业生产迫切需要开展的四个领域的研究，为确保土地利用的可持续性，构建和谐的人地关系提供了决策参考。

Research Advances on Regional Soil Salinization Monitoring in Arid Area

Soil salinization is a problem which threatens arid agricultural production and stability of the oasis ecological environment. It is of great significance for the agricultural production activities and eco-logical security stability to extract salinization information accurately, grasp the salinization of distribution, explore the occurrence of salinization and summarize research methods of the development mechanism of soil salinization in arid area. The change of salinization is not only from natural environment , but also from the deep impact of human activities. With the aggravation of the human activities, its influence become increas-ingly strong.Extracting salinization information effectively , analyzing the formation and driving force of the soil salinization, for soil salinization monitoring which will provide prediction and control methods of salin-ization in additional, which will provide scientific basis for the sustainability of land use and a harmonious relationship between the people and natural.
