Topsoil samples from 61 sites around the Guanting Reservoir, China, were measured for Cu, Zn, Cr, Ni, Cd, Pb and As concentrations. The mean concentrations of Cu, Zn, Cr, Ni, Cd, Pb and As were 16.8, 59.4, 37.8, 18.3, 0.32, 20.1 and 8.67 mg/kg dry weight, respectively. Factors that influence the dynamics of these metals in soils around the watersheds of Beijing reservoirs were examined. The influence of atmospheric deposition, land use, soil texture, soil type and soil chemical parameters on metal contents in soils was investigated. Atmospheric deposition, land use and soil texture were the important factors affecting heavy metal residues. Soil type and soil chemical parameters were also involved in heavy metal retention in soils. The data provided in this study are considered crucial for reservoir remediation, especially since the Guanting Reservoir will serve as one of the main drinking water sources for Beijing in the foreseeable future.
对中国官厅水库周边 61 个地点的表土样本进行了 Cu、Zn、Cr、Ni、Cd、Pb 和 As 浓度的测量。Cu、Zn、Cr、Ni、Cd、Pb 和 As 的平均浓度分别为 16.8、59.4、37.8、18.3、0.32、20.1 和 8.67mg/kg 干重。研究了影响北京水库流域周边土壤中这些金属动态的因素。调查了大气沉降、土地利用、土壤质地、土壤类型和土壤化学参数对土壤中金属含量的影响。大气沉降、土地利用和土壤质地是影响重金属残留的重要因素。土壤类型和土壤化学参数也参与了土壤中重金属的保持。本研究提供的数据被认为对水库修复至关重要，特别是因为官厅水库在可预见的未来将成为北京的主要饮用水源之一。
