China-DNDCSustainable agricultureBiogeochemical modelingDuring the past century Chinese agriculture has been struggling to produce more food to support the ever growing population, while dealing with the increased degradation of air, water and soil quality in the agricultural regions. Lessons learnt from ...

Long-term SOC validation of DNDC in China. The dots of the figure on the right represent field data from the two national soil surveys in China in the 1960s and 1980s. The line represents the simulation results. Sites 1 to 8 in the figure on the left are from Zhanget al. (2006, ...
本文根据贵州省玉米-油菜轮作田、休耕地和大豆-冬小麦轮作田的N2O释放通量及其影响因子季节变化的田间观测结果,对比分析了DNDC模型计算与三试验田田间观测在N2O释放通量及其主要影响因子季节变化上的拟合程度.结果表明,对N2O释放通量、土壤NO3-和NH4+含量、土壤湿度和土温,模型计算结果与田间观测具有相似的季节变化模式和...
基于土壤调查和模型模拟的研究表明, 20世纪30~80年代, 我国农田土壤有机碳储量略有下降[281,282];自80年代以来, 除DNDC模型模拟的碳储量数值有所下降外, 其他方法获得的我国农田土壤有机碳库均呈增加趋势, 表现为明显的碳汇. 从区域分布上看, 我国农田土壤的碳源汇特征具有较大的空间异质性. 我国东部、中部、...
All prior DNDC simulation studies have created one new plant parameter set to represent the steppe community. We create a new crop“TMS-stipa” for the Stipa-dominated temperate meadow steppe. The main parameters of TMS-stipa were obtained from long-term observation data. A Monte Carlo test ...

A computer process simulation model of carbon and nitrogen biogeochemistry in agro-ecosystems (DNDC) was applied to predict nitrogen leaching in the soil layer of agricultural ecosystems at national scale. Data on climate, soil properties, cropping systems, acreage, and management practices at county ...
