氮沉降对森林碳汇功能影响的研究进展

Research Advances in the Effect of Nitrogen Deposition on Forest Carbon Sequestration

氮沉降增加对森林碳汇功能的大小和稳定性具有重要影响。文中介绍了森林碳汇对氮沉降增加响应的研究进展,概述了同位素技术在该研究领域的应用前景,指出在沉降增加条件下森林光合产物分配和土壤碳周转速率变化将是未来森林碳循环研究的热点。

Nitrogen deposition imposes important impact on the function and the stability of forest carbon sequestration.This paper reviewed the research advances in the increasing response of forest carbon sequestration to nitrogen deposition,described the application prospects of stable carbon isotope technique in the research field.And finally this paper pointed out that,on the condition that nitrogen deposition rises,on the allocation of forest photosynthetic products and the change in soil carbon turnover rate are the two hotspots in the future carbon cycling research.
