【摘要】 以2 m×2 m 网格在河南省原阳县黄河大堤南侧5a 生人工杨树林地内正方形区域内采集49个表层 （0～20 cm）土壤样品,研究重金属的空间分布。结果表明,Cu、Mn、Pb 和 Zn 的含量分别为16.53、370.4、66.01和 33.34 mg·kg^-1,变异系数分别为37.2%、19.5%、38.9%和23.1%。4种元素的空间分布均是结构性因素和随机性因素共同作用的结果,其中 Pb 的空间分布受随机性因素影响较大。Cu 和 Pb 的空间分布的表面图表现出部分等值线与大堤方向近似平行的现象。Cu 和 Zn、Cu 和 Mn、Pb 和 Zn 含量的相关性均达到 p<0.05水平。更多还原

【Abstract】 Soil in a poplar（Populus alba L）woods beside the Yellow River bank in Henan province was sampled with 2 m to 2 m grids in a square area（14 m to 14 m）and analyzed for copper（Cu）,Manganese （Mn）,lead（Pb）and Zinc（Zn）.Average contents of these four metals were 16.53,370.4,66.01 and 33.34 mg·kg^-1,their CV were 37.2%,19.5%,38.9% and 23.1%,respectively.Spatial variability of Cu, Mn,Pb and Zn were eontrolled by random factors and structural factors as well,while Pb was more affected by random factors.Part of the isolines of Cu and Pb was parallel with Yellow River bank.Significant linear correlations were found between Cu and Zn,Cu and Mn,Pb and Zn（p<0.05）.更多还原
