中文摘要:

造林和森林管理能增加碳股票并且根据京都协议说明排放减小。地点管理在造林以后在土壤碳的累积上有重要效果。这评论检验地点管理的效果,包括土壤骚乱,授精,变瘦,杂草控制,收获并且烧控制在在种植园的土壤碳动力学上,基于最近的出版结果。土壤骚乱能提高土壤碳损失,与引起大多数和 disking 最少土壤碳的损失的完整的耕作。授精的效果并且在土壤上变瘦碳是不确定的。杂草控制能阻止碳输入未葬残余和根周转和增加玷污温度和土壤侵蚀,它接着在土壤表面上减少碳的数量。有显著地收获紧张和收获残余罐头的保留的增加的土壤碳减少在土壤提高碳的累积。在造林前烧控制为土壤碳有一个短期的好处,但是它不对土壤碳在上的隐遁有益长期。未来研究应该集中于调查地点管理惯例的长期的影响,特别土壤授精并且变瘦在碳上,识别土壤碳的主要功能的水池的反应到管理练习,在长期的土壤碳隐遁理解土壤氮水池和他们的角色的动力学,象确定一样,土壤碳用模型在不同气候条件和地点管理情形下面处理。

英文摘要:

Afforestation and forest management can increase carbon stocks and account for emission reduction according to the Kyoto Protocol. Site management has important effects on the accumulation of soil carbon after afforestation. This review examines the effects of site management, including soil disturbance, fertilization, thinning, weed control, harvesting and controlled burning, on soil carbon dynamics in plantations, based on recent published results. Soil disturbance can enhance soil carbon losses, with whole ploughing causing the most and disking the least loss of soil carbon. The effects of fertilization and thinning on soil carbon are in- conclusive. Weed control can prevent the carbon input from above-grotmd residue and root turnover and increase soil temperature and soil erosion, which in turn reduces the amount of carbon on the soil surface. Soil carbon decreases with the increase of harvest- ing intensity and the retention of harvest residue can significantly enhance the accumulation of carbon in the soil. Controlled burning before afforestation has a short-term benefit for soil carbon, but it is not beneficial to the sequestration of soil carbon over the long term. Future studies should focus on investigating the long-term impact of site management practices, especially soil fertilization and thinning, on carbon, identifying the response of major functional pools of soil carbon to management practices, understanding the dy- namics of soil nitrogen pools and their role in long-term soil carbon sequestration, as well as quantifying soil carbon processes under different climate conditions and site management scenarios using models.
