Abstract: The ecological pollution risk assessment and heavy metal source identification of 11 heavy metals (As, Cd, Co, Cr, Cu, Hg, Mn, Ni, Pb, V, Zn) in soils from mangrove forest in Leizhou Penisula have been respectively carried out by using potential ecological risk index and correlation analysis method.The result shows that the content of heavy metals (Hg, As, Cu, Hg) in individual sampling area exceeded national standard.The average content of 9 heavy metals (As, Cd, Co, Cr, Cu, Hg, Mn, Ni, Zn) was more than the environmental background value.The total potential ecological risk of soil heavy metals is at moderate level in Leizhou Penisula.The Hg element was in strong environmental pollution and the Cd element was in secondary environmental pollution, while other elements were light pollution.From the spatial distribution, the pollution level of heavy metals in soils was in strong environmental pollution in Nanshan and View Sea Corridor sample area, while light pollution in Qishui sample area and secondary pollution in other sample areas.Enrichment of heavy metal elements was closely related to the natural features of soil and man-made emissions.The soils with higher clay content and organic matter content were in the highest potential ecological risk.The regions with more developed industry and strong human activity were more serious in the ecological risk of heavy metal pollution.
