气候变化对陆地生态系统土壤有机碳储量变化的影响

通过研究气候变化对土壤有机碳储藏的影响,对预测未来气候变化下土壤有机碳动态变化与深入理解陆地生态系统变化和气候变化之间的相互作用有着极其重要的意义。本文归纳了土壤类型法、模型模拟法等途径对土壤有机碳储量估算的结果并分析它们各自的不确定性,综述了气候变化对土壤碳贮藏影响机理的研究与相应过程模拟的模型研究进展,并综合分析了当前研究中还存在的问题与不足。

Effects of climate change on soil organic carbon storage in terrestrial ecosystem

To understand the impacts of climate change on the soil organic carbon storage in terrestrial ecosystems is of significance in predicting the changes of soil organic carbon in the future,and the interactions between terrestrial ecosystems and climate change.We presented the approaches of soil profile measurement,soil organic carbon modeling,and others to estimate the soil organic carbon storage in terrestrial ecosystems,and the uncertainty of these estimations.The research progress in understanding the effects of climate change on soil organic carbon storage in terrestrial ecosystems and the modeling of corresponding processes were reviewed,and the estimations of soil organic carbon storage changes under future climate changes were pointed out,with some questions in the estimations put forward.
