China has abundant mineral resources, and with the development and utilization of mines, heavy metal pollution in the soil near mines is increasingly severe. At present, the problem of heavy metal pollution in mining soil is a severe test in China’s environmental governance. These heavy metal elements not only cause serious damage to the soil, plants, water bodies, and crops around the mining area, but also destroy the structure of the soil. Heavy metal ions can remain in soil for a long time and easily enter the human body through the food chain, accumulating in the body, thereby endangering human health and causing some endemic diseases. The occurrence characteristics of heavy metal elements in soil reveal their migration, transformation, and bioavailability. Therefore, understanding the morphological characteristics of heavy metals in soil is of great significance for evaluating the degree of metal pollution. This article provides a comprehensive overview of the research progress and pollution sources related to heavy metal pollution in domestic mining soils. It delves into the advantages and disadvantages of commonly used heavy metal form extraction methods (Tessier five-step extraction method and BCR continuous method) and makes prospects for the research content, research directions, and future trends of form extraction methods for soil heavy metal pollution. %K 土壤重金属， %K 来源， %K 赋存形态
