果园生态系统碳循环规律研究进展

系统阐述了近10余年来果园生态系统碳循环规律的相关研究,得出以下结论:土壤是果园生态系统最大的碳库,碳储量占总体的70%以上;果园生态系统碳输入量大于碳输出量,是碳汇;经营管理措施对碳吸存影响较大,通过增施有机肥、生草、覆盖以及免耕等经营措施不但可以增加系统碳汇,减少碳排放,还可以提高果园土壤肥力。

Review of Characteristics of Carbon Circle in Orchard Ecosystem

Several studies were reviewed by this paper about carbon circle of orchard ecosystem in the past ten years,and some conclusion can be drawn that： firstly,the carbon in the soil,account for more than 70%,is the biggest carbon stocks of the orchard ecosystem;Secondly,the orchard ecosystem,as a carbon sequestration,contributes to the decrease of CO2 in the atmosphere.Thirdly,the carbon storage was influenced by orchard management,that is to say,Adopting some strategies not only can increase the orchard ecosystem carbon sequestration but also can improve soil fertility,including manure application,ground covering plant,growing grass,no-tillage practices and so on.
