植被恢复对土壤碳氮循环的影响研究进展

植被恢复重建是治理水土流失的主要手段之一，能够有效地促进侵蚀土壤发育、提高土壤肥力、增强土壤微生物活性，进一步影响土壤碳氮循环.因此，植被的恢复重建过程对土壤有机碳库、氮库累积以及温室气体的排放具有一定作用.本文综述了植被恢复对土壤碳、氮循环过程的影响以及土壤质量与植被修复之间的协同效应，并提出了今后进一步研究的方向.对评价植被恢复在应对全球气候变化中所起的作用具有借鉴与参考价值，对促进土壤肥力改善和退化生态系统的恢复及可持续发展也有重要的现实意义.

Effects of vegetation restoration on soil carbon and nitrogen cycles: A review.

Vegetation rehabilitation is one of the main means in managing soil and water loss, being able to effectively promote the development of eroded soil, improve the soil fertility level, enhance the soil microbial activities, and in further, affect the soil carbon and nitrogen cycles. Therefore, vegetation rehabilitation plays definite roles in the accumulation of soil organic carbon and nitrogen pools and the mitigation of greenhouse gases emission from soil. This paper summarized the effects of vegetation rehabilitation on the soil carbon and nitrogen cycles and the synergetic effects between soil quality and vegetation rehabilitation, and put forward the further research directions, which could provide the reference for the evaluation of the roles of vegetation rehabilitation in response to global climate change, and the practical guidance for the improvement of soil fertility and the reco very and sustainable development of degraded ecosystems.
