Soils play a critical role in the global carbon cycle, and can be major source or sink of CO_2 depending upon land use, vegetation type and soil management practices. Fine roots are important component of a forest ecosystem in terms of water and nutrient uptake. In this study the effects of thinning and litter fall removal on fine root production and soil organic carbon content were examined in 20-year-old Masson pine (Pinus resinosa) plantations in Huitong, Hunan Province of China in the growing seasons of 2004 and 2005. The results showed that fine root production was significantly lower in ...

土壤在全球碳周期起一个关键作用，并且能是取决于土地使用，植被类型和土壤管理惯例的 CO2 的主要来源或水池。好根以水和滋养的举起是一个森林生态系统的重要部件。在这学习在好根生产和土壤上变瘦和崽秋天移动的效果器官的碳内容在 20 岁的马森松(Pinus resinosa ) 被检验在 Huitong 的种植园，在 2004 和 2005 的成长季节的中国的湖南省。结果分别地证明那好根生产比在控制情节在变瘦的情节是显著地更低的，与在 2004 和 2005 个成长季节的 58% 和 14% 的减少。崽秋天移动显著地在 2004 增加了好根生产 14% 。土壤温度(Tsoil ) 和土壤潮湿(Msoil ) 比在控制的那些在变瘦的情节是更高的。崽秋...
