摘要
综合国内外研究现状,对草地生态系统N循环过程、N素添加、N的环境影响因素、盐渍化与N相关性的研究现状及进展进行了综述,并对存在的问题和前景进行了分析和展望,旨在充分发挥草地生产潜力、探索其适应性管理措施,为寻求效果最佳、成本最低、耗时最短的盐碱地改良方法提供理论依据。
Research progress and status of grassland nitrogen cycle,nitrogen addition,environmental impact factors and the relationship between saline-alkali and nitrogen were summarized on the basis of comparison and analysis of domestic and international studies.The problems existed in current researches were reviewed and the future researches were prospected aiming at exploiting the potential productivity of grassland,exploring the adaptive management measures,providing theoretical basis for seeking most effective,lowest cost,least time consuming on saline-sodic soil amelioration.
