土壤有机碳、氮动态模型研究进展

Discussion on Dynamics Models of Soil Organic Carbon and Soil Organic Nitrogen

土壤有机质的含量、分解、合成等动态变化与土壤质量有着密切的联系。SOM模型为定量研究土壤有机质动态变化过程及其变化机制提供了有效途径。本文对国内外现有的土壤有机碳、氮动态模型进行了综述,并对应用最广泛的Century模型、RothC模型以及DNDC模型进行评述,分析了现有SOM模型存在的问题及未来的发展趋势。

There is closely relationship between soil quality and its dynamics, which contains the content, decomposition, composition of the soil organic, etc. SOM models have supplied efficient approaches for quantitative description of the process of soil organic matter dynamics. An overview of existing soil organic carbon and nitrogen dynamics was summarized. It also evaluated the most widely-applied models, such as Century, RothC and DNDC. The future development of existing SOM models were analyzed.
