Assessing Nitrate Leaching With GLEAMS Model in an Agricultural Small Catchment in Southeast China. [PDF]
, 2007 应用GLEAMS模型估算我国东南亚热带地区农业小流域硝态氮的渗漏淋失。在五川流域8种不同土地利用方式的农田中埋设渗漏监测装置,每月采集水样分析硝态氮含量。用2002年4—12月作物生长季节的实测数据进行模型校验的结果表明,模型对水稻田除外的其他土地利用方式下硝态氮渗漏淋失模拟效果较好。五川流域2002年硝态氮淋失模拟计算结果表明,不同土地利用方式下硝态氮淋失时空差异显著,全年渗漏量(以氮计)为4.6438.39 kg.hm-2,流域面积加权平均为29.99 kg.hm-2。甘蔗地 ...
