农业微环境对土壤温室气体排放的影响

Influence of agricultural micro-environment factors on greenhouse gases emission from the soil

二氧化碳(CO_2)、氧化亚氮(N_2O)、甲烷(CH_4)等气体排放量的增加所引起的温室效应是全球变暖的主要促动因素。同时各种温室气体的产生和排放量也同样受其所处环境状况的影响与反馈作用。研究各环境要素对土壤温室气体排放的主要影响机制是调节气候变化与温室气体排放循环反馈过程的关键环节,对减少温室气体排放、减缓全球变暖趋势具有较强的现实意义。阐述了土壤排放N_2O、CH_4对环境因素的影响,并提出温室气体减排措施。

The global warming is one of the environmental problems. The global climate change is the result of the natural process and human activity. The increasing of carbon dioxide, nitrous ox-ide and methane' emission flux is the main impelling force. At the same time, the emission of the greenhouse gases (GHG) are also affected by the environment, so the study on the environment influence mechanism is the key link of keeping abreast of the interaction between the climate change and the GHG emission. It is of important realistic significance for decreasing the emission of the GHG and slowing down the global warming pace. In this paper, we will generally discuss about the influence of the environment factors and put forward some measures that could control and retard the GHG emission.
