    准东地区不同区域土壤重金属关联性分析及空间分布

    Correlation analysis and spatial distribution of soil heavy metals with different regions in Zhundong area

    • 摘要: 本文以准东地区的五彩湾、荒漠带和将军庙区域为研究靶区,运用多元统计分析及空间分析法,对准东地区的五彩湾、荒漠带和将军庙区域之间的土壤重金属进行关联分析及空间分布。结果表明:Hg、As元素在这三个区域变幅较小,土壤重金属含量较为集中,相比之下Cu、Cr、Pb和Zn元素变幅较大。由主成分分析得,这三个区域均提取了四个主成分;Hg、As、Cu、Cr、Pb和Zn元素是影响五彩湾与荒漠带区域土壤重金属含量的主要因素;As、Cu、Cr和Pb元素是影响将军庙区域土壤重金属含量的主要因素。通过对不同区域的土壤重金属相关性分析得,五彩湾区域土壤Zn元素与将军庙区域土壤Zn元素呈显著性负相关,其中相关系数为-0.753,荒漠带区域Cr元素与将军庙区域的Hg、Cr元素均呈显著性正相关,其相关系数分别为0.776、0.751,显著性水平相关p< 0.01,荒漠带区域的Cu元素与将军庙的Pb元素具有显著性正相关,相关系数为0.792。进而对显著性相关的元素进行拟合可知,将军庙区域的Hg元素与荒漠带地区的Cr元素三次拟合关系最好,相关系数R2=0.9491。各元素空间插值明显,高值区域主要分布在五彩湾和将军庙区域。

       

      Abstract: In this paper,the Wucaiwan,desert zone and Jiangjun temple in Zhundong region was used as the research target and used multivariate statistical analysis and spatial analysis method for correlation analysis and spatial distribution of soil heavy metals between Wucaiwan,desert zone and Jiangjun temple in Zhundong.The results showed that the amplitude of Hg and As were low in these three region,soil heavy metal content was more concentrated,on the contrast,the amplitude of Cu,Cr,Pb and Zn were high.The three regions were extracted four principal components by PCA;Hg,As,Cu,Cr,Pb and Zn elements were the main factors that affected the contents of heavy metals in the soil area of the colorful Bay and the desert.As,Cu,Cr and Pb elements were the main factors that affected contents of heavy metals in Jiang Jun Temple.By analyzing the correlation of soil heavy metals in different regions,Zn elements in Wucaiwan were negatively correlated with Zn elements in Jiangjun temple,and the correlation coefficient was -0.753,Cr elements in the desert zone and Hg,Cr elements were significantly positive correlation in Jiangjun temple,the correlation coefficient were 0.776,0.751,significant level of correlation p< 0.01,Cu elements in the desert zone and Pb elements had a significant positive correlation in Jiangjun temple,the correlation coefficient was 0.792.then the significant correlation elements were fitted,three fitting relation between Hg elements in Jiangjun temple and Cr elements in desert zone were the best,and the correlation coefficient R2=0.9491.The spatial interpolation of each element was obvious,and the high value area was mainly distributed in Wucaiwan and Jiangjun temple.
