农田甲烷排放研究进展

甲烷是一种重要的温室气体,而农田是甲烷的重要排放源之一.因此,对农田甲烷排放进行研究具有重要的意义.该文从农业生态系统甲烷排放、土壤甲烷排放的影响因子,比如土壤含水量、土壤性质以及施用肥料的种类及肥料施用方法等方面综述了稻田甲烷的研究进展.探讨了缓解农田甲烷排放的管理措施,尤其是减缓稻田甲烷排放的措施.提出了未来开展稻田甲烷的研究方向,以期为进一步控制稻田甲烷排放提供一定参考.

Research Progress on Methane Emission from Cropland

Methane is an important greenhouse gas,and farmland is one of the important emission sources of methane.Therefore,it's important to study the discharge of methane from cropland.This paper reviewed the methane emission from agricultural ecosystem,the factors controlling CH4 fluxes from soil,such as water regime,the soil characteristics,and the type and amount of applied fertilizers and so on,the management for mitigation of CH4 emission from cropland,especially from paddy field,and put forward some research suggestions on methane emission in the future.The objective of this paper is to provide reference for controlling methane emission in cropland.
