Chenzhou City is located in the Nanling Mountains, characterized by a highly undulating terrain and complex parent rock types. The soil is predominantly red and yellow soil, exhibiting significant vertical differentiation. The regional soil-forming parent materials generally contain non-ferrous metal elements, resulting in relatively high natural background levels; at the same time, large areas of selenium-rich soil are distributed throughout the region. Due to the impact of mineral extraction, heavy metal accumulation occurs in localized areas, leading to strong spatial heterogeneity in the soil.
This soil spatial dataset covers soil types, soil layer thickness, pH, organic matter, selenium, lead, cadmium, and other physicochemical and heavy metal indicators, along with supporting geographic information such as sampling locations and spatial boundaries.
This dataset provides a comprehensive understanding of the region’s soil environmental baseline, supporting the assessment of arable land quality, the development of selenium-rich lands, and the management of soil pollution risks. It also serves as a foundational data resource for Chenzhou City’s territorial spatial planning, ecological conservation and restoration, and the sustainable development of specialty agriculture.
