| 摘 要： | 为了缓减黄河水资源日益短缺的局面,提高内蒙古引黄灌区的灌溉水保证率,以乌拉特三湖河灌域为研究对象,从2010年开始开展井渠双灌试验。结果表明:在实际运行中,井渠双灌起到了在灌溉紧张期缓解用水矛盾的作用,改善了地下水水质,但通过两年来的运行,出现了地下水采补不平衡形成漏斗的情况,并由于开采地下水水费没有开征,使用井灌成本低,灌溉方便及时,导致井灌面积不断扩大,引黄灌溉面积逐渐萎缩,地下水得不到有效补充,致使采补失衡,长此下去必将威胁三湖河灌域的可持续发展和生态平衡。

| Abstract: | In order to alleviate the current situation of shortage of water resources of Yellow river and improve the irrigation water as-surance of Inner Mongolia yellow-river irrigation district,take the Wulate Sanhuhe irrigation field as research obj ect,the well-chan-nel irrigation experiment was carried out in 2010.The results showed that the well-channel irrigation relieved the water contradiction in tension period.Improving groundwater quality.Through the operation of two years,the funnel was formed because of the imbal-ance of mining and filling groundwater.Not imposing the water fee of exploiting groundwater and the low cost of well irrigation made the well irrigation area continuously extend.The area of Yellow river reduced gradually.The groundwater could not get the effective supplement which led to the imbalance between mining and filling.This condition would threat the sustainable development and eco-logical balance of Sanhuhe irrigation field. |
