Heavy Metal Contamination Characteristics of Greenbelt Soil and Tree Enrichment in Harbin City, China

Abstract:

Soil heavy metal contamination (SHMC) in greenbelt functional areas and their enrichment characteristics in 7 tree species were evaluated. The results showed that Cd contamination is the heaviest in all 4 heavy metals. The pollution level decreases in following order: Industrial Park Greenbelt (IPG), Urban Road Greenbelt (URG), Greenbelt along Both Sides of Songhua River (GBSSR), City Park Greenbelt (CPG), Agricultural Land (AL), Forest and Nursery Greenbelt (FNG). As for Zn, Cu and Cd contaminants, the bioconcentration factor (BCF) of Populus lasiocarpa is higher than other species, therefore, it should be selected as an important species to repair heavy metal polluted soil; the other tree species with relatively lower BCF can be selected as reserved tree species.
