黄土高原旱塬农田生态系统碳、氮循环特征

Study on the Carbon,Nitrogen Cycling characteristics of dry farmland ecosystem on Loess Plateau

  • 摘要: 以黄土高原南部长武试区的典型旱塬农田生态系统为研究对象,运用DNDC模型分析其麦田在4种处理下连续6年的C、N循环特征,经与已知试验结果和实测数据比较,验证了该模型的适用性,并堤出了该区农业发展主要措施。

     

    Abstract: Taking the typical farmland ecosystem of Changwu Demonstration Area in the south of Loess Plateau as the study object,based on the using of DNDC(Denitrification-decomposition) model,the carbon and nitrogen cycling characteristics of wheat field ecosystem in four different dealing through successive six years were analyzed.And also by comparing with known experimental results and practical measuring data.it was preliminarily verified that the model was applicable.On the basis of these,the main managements for agricultural development in the future were proposed in the area.
