本文综述了泰国东北部盐渍地的特征、面积分布、盐渍化原因、现有原生植被、盐渍化对植物生长和分布的影响、盐渍地对周边环境的影响及盐渍地治理试验。提出并讨论了恢复该区域这些退化土地的另一种办法。建议采用农林业模式，即“农林业-水文地质系统”，是恢复这一特定区域受盐影响土地的最适当战略。鼓励对这一具有挑战性的领域进行进一步的研究和研究，以发现最有效和适用于该地区的方法。这些新开发的方法与泰国土地发展部已经采用的现有技术结合使用，应能成功地恢复退化的土地。
This paper reviews the characteristics, area distribution, causes of salinization, existing native vegetation, effects of salinity on plant growth and distribution, as well as on surrounding environments and their ameliorating trials of salt affected lands in Northeast Thailand. An alternative approach for the rehabilitation of these degraded lands in the region is proposed and discussed. An agroforestry pattern, namely “agro-sylvo-hydrogeological system” is suggested to be the most appropriate strategy for the rehabilitation of the salt affected lands in this particular region. Further study and research in this challenging field is encouraged in order to discover the most effective and applicable method for this region. Used in conjunction with the available techniques already adopted by the Land Development Department of Thailand, these newly developed methods should be successful in rehabilitating the degraded lands.
