摘　　要：针对韩墩引黄灌区实施浑水灌溉后大量泥沙入田的现实情况,为了预控土壤沙化,实现田间科学利用泥沙,精准改良土壤,研究提出了沙化参数的概念,以表征引黄灌区浑水灌溉可能造成土壤沙化的程度;提出了测土配沙改良土壤运行模式及科学配沙工程技术措施。其中,科学配沙工程技术措施包括两种:一是为改良砂质土壤,增加砂质土壤的保水性,利用泥沙沿垂线下粗上细的分布规律,设计了分层取水取沙的工程技术措施;二是为有效改善黏质土壤的透气性能,提出了导沙技术措施。As to the mode of muddy irrigation transporting sediment to farmland in Handun irrigation area, for early warning and controlling soil desertifieation, and then scientifically applying sediment to improve the soil of the irrigation area, the desertification parameters was sug- gested, which could describe the extent of the desertification. A new sediment allocation mode and an engineering technology were suggested. The engineering technology of sediment allocation consisted of two parts. One was an engineering installation which diverting water from differ- ent heights, in order to improve water retaining capacity of sand soil. This engineering was based on the rule that the particle size of sediment below the river was larger than that of sediment in upper water. The other technical measure was diverting sediment to improve the porosity and permeability of clay soil.
