干旱区灌溉用水模型的研究

The Irrigation water model in arid region

干旱区农业用水最显著的特点是季节性强，无灌溉即无农业。合理利用干旱区有限的水资源，保证农业可持续发展，是农业高效用水中有待解决的课题之一。以内蒙古河套灌区解放闸灌域为代表性地区，结合其自然条件，建立了该地区灌溉用水中长期预报模型。所建模型对于合理利用干旱区有限水资源，提高引水效益，保证农业可持续发展，是一种重要的措施。

based on the data of irrigation water of Irrigation Management Bureau of Jiefang Sluice Area in Inner Mongolia, the medium and long term mirrigation water model and the model of agricultural input and output in arid region have been created. These models plays important role in rational and use of limited water resources and raising water use efficiency in arid regions.
