摘  要:
以典型低湿地水田为研究对象,采用美国新罕布什尔大学李长生教授提出的一种生物地球化学模型DNDC来模拟湿地生态系统中土壤-植物-大气之间碳氮的循环。结果表明,湿地土壤有机碳的输入为523.8 kg.hm-2,主要是作物残留的秸秆和根系;土壤N的输入为197.9 kg.hm-2,土壤有机碳的输出为13 508 kg.hm-2,土壤N的输出为411.8 kg.hm-2。由于人为的影响,土壤C的亏损很大,N的输入输出也不平衡。

摘  要:
In the present study,we utilized the DNDC model that was invented by Professor Li Changsheng to study the carbon and nitrogen cycling in the soil,plant and atmosphere systems.The results indicated that the input of organic carbon in the studied soil was 523.8 kg·hm-2,while the input of nitrogen in the soil was 197.87 kg·hm-2;the output of organic carbon in the soil was 13 508 kg·hm-2,while the output of nitrogen in soil was 411.83 kg·hm-2.
