摘　　要：水库清淤可以恢复水库原有的蓄水能力,清淤后若淤积物处理不当,会占用大量土地资源,对生态环境造成二次污染。为研究水库淤积物的资源化利用,以陆水水库为例,对陆水水库进行定点取样,并对样品进行现场和室内实验室分析。将分析结果与相关规范及全国第二次土壤普查制定的土壤养分分级标准等进行对比,结果表明:水库湖心底取样S1~S10的各种重金属含量均小于建设用地(第二类用地)风险管制值和农用地(水田)风险管制值,可以将水库清淤底泥较好地用于矿山复绿工程;水库砂及卵砾石可用做建设材料,支持和保障区域社会建设发展以及重点工程和民生工程的建设等。Reservoir desilting can restore the original water storage capacity of the reservoir,but if the sediment is not properly treated,it will occupy a lot of land resources and cause secondary pollution to the ecological environment.In order to research the resource utilization of reservoir sediment,we took Lushui Reservoir as an example to conduct the spot sampling,and analyzed the samples in field and laboratory.The analysis results were compared with some standards and the soil nutrient classification standards formulated by the second national soil survey.The results showed that the contents of various heavy metals in S1 to S10 sampled from the bottom of the reservoir lake were lower than the risk control values of construction land(the second type of land)and agricultural land(paddy field).It showed that the sediment of reservoir can be used in mine greening project.Sand and gravel can be used as construction materials,which can well support the development of regional social construction and key projects and livelihood projects construction.
