氮在森林生态系统中是限制植物生长的重要元素,进行森林生态系统内氮矿化、氮饱和和氮循环的研究对于了解森林生态系统的生产力、养分循环和转化具有重要意义。本文比较和分析了国内外近10余年来的相关文献,对国内外氮矿化、氮饱和和氮循环的研究进展以及研究现状进行综述,对现在研究存在的问题和未来研究提出建议和展望。参58。 Nitrogen is an important element that limits plant growth in forest ecosystems. Studying nitrogen mineralization, nitrogen saturation and nitrogen cycle in forest ecosystems is of great significance for understanding the productivity, nutrient cycling and transformation of forest ecosystems. This paper compares and analyzes the related literatures at home and abroad in the past 10 years and reviews the research progress and research status of nitrogen mineralization, nitrogen saturation and nitrogen cycle at home and abroad, and puts forward suggestions and prospects for the existing research and future research.
