Abstract

Abstract

By collecting and analyzing the heavy metal elements insurface (0~20 cm) and deep (160~200 cm) soil samples in southeastern suburbs of Beijing, the distribution characteristics of elements in soil in this area were ascertained.The spatial autonomy of heavy metal elementswas explored by establishing a semivariogram model. The enrichment characteristics of elements in surface soil were discussed,as well as the correlation of the enrichment coefficient. On this basis of the research, the significant enrichment areas of heavy metal elements are divided, and the reasons for the enrichment are explained and analyzed in depth.The results show that:The content levels of Cd, Cu, Hg, Pb, and Zn in surface soil of the study area are significantly higher than those in the deep layer, with a gap of 1.2 to 3.9 times. Compared with soil’s heavy metal content in Beijing and China,, the soils in the study area is relatively rich in Cd and Hg. As it was affected by many factors such as the source of soil-forming parent material and human activities, the spatial autocorrelation of As and Cr in surface soil is strong, and the spatial autocorrelation of Cr in the deep soil is weak. The spatial autocorrelation of other elements in the surface and deep layers is medium. As, Ni, and Cr in the surface soil are weakly enriched.But Cu, Pb, Zn, Cd, Hg are strongly enriched, and Hg is the most enriched. Based on the enrichment coefficient, five significant enrichment areas of heavy metal elements are delineated.The division of this area clearly reflects that human life, agricultural planting, and industrial production are important factors that cause the accumulation of heavy metal elements in surface soil.Therefore, it is necessary to pay close attention to the distribution of soil elements in human settlements, agricultural planting areas, and industrial enterprise distribution areas. The purpose is to prevent the deterioration of the soil environment and ensure the safety of the ecological environment.
