摘要： 三江平原是我国面积最大的湿地分布区,经多年开垦现已发展成为我国重要的商品粮基地。由于开垦后下垫面条件发生了很大变化,加之农业生产活动的影响,使本区土壤氮循环发生了根本性的改变。以三江平原地区典型低湿地大豆田为研究对象,采用美国新罕布什尔大学李长生教授所提出的一种生物地球化学模型DNDC来模拟农田生态系统中土壤-植被-大气之间氮素的循环,以及温室气体N2O的排放规律。

Abstract: The Sanjiang plain is the largest wetland area in China. After many year’s reclamation, this region has become an important commodity soybean base. There is a great change of soil nitrogen circulation in this region; it was made by the change of surface condition and influence of agriculture. This paper focuses on the lowland soybean field, using the DNDC model that was made by Professor Li Changsheng to study the nitrogen circulation in the soil, plant and atmosphere systems, as well as the law of nitrous oxide emission.
