研究滴灌条件下土壤CO2和N2O的排放特征及其影响机制，有助于深刻了解灌溉方式变化对农田生态系统碳氮循环的影响，对农业灌溉管理措施的改进和农业温室气体减排具有重要的意义。本文综述了滴灌对农田土壤CO2和N2O排放的影响，从土壤水分、土壤温度、土壤养分和土壤结构等方面分析了滴灌条件下农田土壤CO2和N2O产生和排放的主要影响机制，在此基础上探讨了滴灌对大气温室效应影响的不确定性以及目前研究中存在的主要问题。

The research on the effect of drip irrigation on the emission of CO2 and N2O and its impact mechanism was helpful to understand the influence of irrigation pattern changes on carbon and nitrogen cycles of agro-ecosystem. And they were also significant for the improvements of agricultural irrigation management and mitigation in greenhouse gas emission. In this paper, different impacts of drip irrigation on CO2 and N2O were summarized and the influence mechanism of soil moisture, soil temperature, soil nutrients, soil structure and soil microorganism on the production and emission of CO2 and N2O from agricultural soil were analyzed. Meanwhile, the uncertainties in the influence of drip irrigation on atmospheric greenhouse effec as well as the existing problems of current research were also discussed.
