| 摘 要： | 本文对N2O、CO2两种温室气体的研究工作进行了评述，重点介绍了土壤脱氮-分解模型（DNDC）的起始原由、发展过程及其结构.并通过对模型在不同国家和地区的灵敏度检验，表明与实测结果非常吻合，得出了非常重要的结论.这一模型不仅对N2O、CO2等温室气体的全球变化研究有重要意义.而且对土壤农业耕作实践也有指导作用，但这些结论有待于进一步的详细研究.

| Abstract: | The N2O and CO2 greenhouse gases are reviewed in this paper. DNDC model, especially its origin, process and structure, is introduced in detail. Sensitivity tests, which are proceeded (or proceeding) in different countries and regions, are consistent with field and experimental results reported in the literature. It has proved that the DNDC model has not only far-reaching significance for the global change research of the greenhouse gases but also important-realistic tutorial function for the agriculture practice. However it is necessary that further study should be made on all the conclusion. |
