Sažetak

In recent years, extensive research has been done on phytoremediation technology, but the study on repair mechanisms and the migration path of heavy metal contaminants in woody plants is particularly rare. The object of this study was Pan Yi mine reclamation area in Huainan as an example of cadmium (Cd) content within different parts of woody plants tissue. Based on the research findings about the migration path, the paper uses statistical methods to carry out the analysis by multiple models. Statistical methods applied multiple trend analysis: linear and logarithmic, and also conic, cubic, and compound curve, power exponent, S curve, growth and exponential regression model. The findings show that Cd is enriched along the root-stem-branch-leaf path in woody plants system in the form of cubic curve, i.e. y = b₃x3 + b₂x2 + b₁/x + b₀. The findings reveal that the enrichment capability of Cd in various parts of the same species of woody plants is different and this is also the case in different species.
