Spatial Distribution of Heavy Metals in Soybean Plantation Soils in Central Sanjiang Plain

Abstract:

Monitoring and analysis of the content of five heavy metals (i.e., Cd, Hg, As, Pb and Cr) in soybean plantation soils in central Sanjiang plain were conducted using the geographic information system (GIS). Statistical analysis indicated, strong intensities of spatial correlation among As, Cr, and Pb, whereas moderate intensities of spatial correlation were observed between Cd and Hg. Therefore, the content and the spatial distribution of the heavy metals are primarily affected by the parent material, topography, soil properties, and other internal factors. However, the effect of external factors, such as industrial pollution, farming methods, as well as the application of pesticide and fertilizer, should also be investigated.
