摘　　要：为了研究水库泥沙资源化的过程,基于水库泥沙淤积形态,结合水库泥沙的离散性、吸附性、可搬运性等基本属性,分析了泥沙淤积的分布特点和主要特征;以自然资源的概念和属性为基础,指出水库泥沙具有多用性、可控性和有限性等资源属性,进而分析了水库泥沙资源化的迫切性及可行性;提出在满足一定的技术要求和社会条件下,水库泥沙是可以资源化的。结合实践经验,从工程材料应用、造地与土地改良、河道防洪与整治等方面,进一步总结了水库泥沙资源化的途径。To explore how to utilize or reclaim reservoir sediment as a natural resource, we present a study of the silt deposit in reservoirs focusing on its spatial distributions and main characteristics, based on the previously measured forms of sediment accumulation in typical reservoirs and considering dispersion, adsorption, transportation, and other properties of reservoir sediment. Using the concept and attributes of natural resources, we demonstrate that the sediment accumulated in reservoirs is characterized by the same attributes as those of natural resources in terms of versatility, controllability, and short supply. Effective utilization of reservoir sediment is feasible and the urgency of doing it is emphasized in this paper. Reservoir sediment can be used as a kind of natural resources if certain technical and social conditions are satisfied. Combined with practical experiences, this paper suggests several engineering approaches to reservoir sediment utilization such as to be used for construction materials, land reclamation and improvement, and flood control and regulation.
