摘要

The four important factors which influence the distribution of heavy metals in soil were ascertained, i.e. soil compaction, the pH of soil, soil organic matter as well as soil microorganisms. The Pearson Correlation Coefficient method was applied to infer how pH affects the distribution of heavy metals, the correlation degree between organic matter and the distribution of heavy metal, the connections between compaction and heavy metal pollution, along with the relevancy between microorganism and heavy metal pollution were analyzed. The results showed that: ➀ The soil pH, soil organic matter and soil compaction of the filling reclamation sites all only have slight relativities with heavy metals, and correlation coefficient are between −0.6 and 0.6. To a certain extent, it also accounts for that the spatial distribution of heavy metals has no regularity. ➁ Soil microorganisms have quite high relativity with soil heavy metals and this presents much more obvious at a coal-fly-ash site. The quantity of microorganisms had a direct effect on the heavy metal content of soil.
