摘要 以排水模型(DRAINMOD)为基础发展起来的排水氮运移模型(DRAINMOD N),可用于研究排水系统对作物生长和各水文要素的影响,以及农田排水土壤中硝态氮的运动和去向,适用于浅地下水位和较湿润地区。本文对模型的氮运移原理和参数输入要求进行了详细描述,采用加拿大安大略省南部EugeneF.Whelan试验站自由排水和控制排水 地下灌溉两种水位管理条件下,1992~1994年3年来的地表径流和地下排水水量及硝态氮损失观测值对模型进行了模拟验证。图形显示和统计参数指标分析表明,模拟值与观测值拟和较好,表明模型具有良好的模拟性能,可用于预测地表、地下排水量和硝态氮的损失,是评价不同农业管理措施对土壤中氮运移的有效工具。 Based on the DRAINMOD(DM)model for simulation of drainage the DM-N model is developed.The new model not only studies the impact of drainage system on crop growth but also the movement and fate of nitrogen in soil.The requirement of parameter input for the model is described.The validity of the model is verified by field observation data collected from Eugene F.Whelan Experimental Station,Canada.It shows that the proposed model is effective for predicting the surface runoff,subsurface drainage and nitrate loss.
