| 摘 要： | 农田SPAC系统水分通量的研究对提高农业用水效率,缓解我国的水资源短缺现状具有重要作用.本文利用HydruS-1d模型,以山西省运城市董村农场为例,估算了研究区三种主要农作物(夏玉米、棉花和冬小麦)的农田水分通量.结果表明,在模拟期内,夏玉米、棉花和冬小麦的作物蒸腾占蒸散发(T/ET)的比值分别为84.7%、71.6%...

| Abstract: | Studies on the water flux in SPAC system of farmland are vital to improve the utilization efficiency of agricultural water,and alleviate water shortage in China.In this paper,the Dongcun Farm in Yuncheng,Shanxi Province is taken as an example to estimate the water flux for three main crops(summer corn,cotton and winter wheat) using Hydrus-1d model.For the growing season of summer corn,cotton and winter wheat,the model is built based on soil water movement,root water uptake model and evapotranspiration model... |
