草地土壤有机碳储量影响因素研究进展

A Review on Influencing Factors of Grassland Soil Organic Carbon Storage

草地土壤有机碳是全球碳循环的重要组成部分,其储量的高低与大气CO2浓度密切相关。笔者综述了近几年有关草地土壤有机碳储量影响因素研究进展,主要介绍了气候条件,草地土壤理化性质以及人为干扰等3方面对草地土壤有机碳储量的影响,阐明了研究影响草地土壤有机碳储量因素的重要意义,为研究如何增加草地土壤有机碳储量提供参考,以有效应对全球气候变化。

Grassland soil organic carbon （SOC） is an important part of global carbon cycle, and its storage is closely related to the concentration of atmosphere carbon dioxide （CO2） content. The author reviewed the research progress of influencing factors of grassland soil organic carbon storage in recent years, including climate conditions, grassland soil physical and chemical properties and human management practices. The author also emphasized the research importance of influencing factors of grassland soil organic carbon storage and the results could provide reference to increase grassland soil organic carbon storage to cope with the globalcli mate change.
