Forest is a complex system of woods, plants, animals, and other environmental components. However,owing to unsustainable population growth and rapid economic development, large quantities of poisonousheavy metal elements are directly or indirectly released into forests by human activities, which hasdamaged the soil quality. This study took Jin-Jing-Ji region of China as an example to analyze thehazards and sources of heavy metals in forest soil. Related literature on heavy metal pollution of forestsoil was analyzed. Subsequently, control measures were proposed to overturn the current pollutedstate of the above region’s forest. Results show that the effect strength, urbanization, andindustrialization level of human activities are closely related to the degree of heavy metal pollution offorest soil. The hazards of heavy metals pollution to forest soil manifest in four aspects: plants, soilanimals, soil enzymes, and people dwelling around the forest. Meanwhile, the main sources of heavymetal pollution are atmospheric dry and wet deposition, industrial activities and transportation, fertilizationof man-made forest, and mining activities. The current state can be improved by employing controlmeasures such as economic and industrial structural adjustments, strengthening the environmentalawareness of individuals, strict control of pollution sources through prevention management, andstrict control of atmospheric deposition and forest pollution. The findings of this study can serve as asignificant reference for relevant regions when analyzing the state of heavy metal pollution to theirrespective forest soils and when conducting environmental diagnosis and forest protection activities.
