| 摘 要： | 从土壤碳含量的输入和输出两方面综述了N沉降胁迫对土壤碳库的影响方式和过程,分析了目前N沉降对凋落物分解、细根生物量、土壤呼吸的影响的研究进展及其作用机制,但由于N沉降对土壤碳库的影响是一个复杂的综合作用过程,N沉降对森林土壤碳库的总效应尚需要更深入的研究.

| Abstract: | Soil carbon pool in terrestrial ecosystems, the largest carbon pool, plays an important role in the global carbon cycle. Summary was made on impact pattern and process of nitrogen deposition on soil carbon pool from the import and export of soil carbon content, as well as on the latest progress of researches on effect of nitrogen deposition to litter decomposition, fine root biomass and soil respiration. Propositions were offered to enhance further research of the response of soil carbon pool to N deposition and the reciprocity of various factors due to the complex relationship. |
