农田土壤N_2O排放的主要影响因素及减排措施研究进展

Key influencing factors and mitigation measures of nitrous oxide emission from agricultural soil

对农田土壤N2O排放的主要影响因素(包括土壤含水量、土壤pH值、土壤温度、土壤质地和肥料施用等)、已有农田土壤N2O排放减排措施及估算模型的研究进展进行了总结分析,并指出了今后研究的重点和方向:(a)探究农田土壤N2O排放的内在机制;(b)提高预测模型的精度;(c)提出科学合理的减排措施.

The new research progress of nitrous oxide emission from agricultural soil was summarized and analyzed, including the key influencing factors （soil moisture, pH value, soil temperature, soil texture and fertilization）, mitigation measures and models. The key points and orientation of future researches were put forward as follows： to discover the inherent mechanism of nitrous oxide emission, to improve the accuracy of models, and to propose the scientific and reasonable mitigation measures.
