The study looked at how organic carbon is distributed in different soils in Binggou Valley. They found that gray brown forest soil had the highest organic carbon content, indicating it's good for storing carbon. The amount of organic carbon decreased with soil depth. The researchers also found that human activities can easily reduce the storage capacity of organic carbon in the soil. Improving vegetation coverage can help protect the environment and reduce erosion. As soil depth increased, organic carbon content decreased while soil bulk density and pH increased. The study showed that organic carbon content is related to fieldwater capacity, total N content, CEC, aggregate percentage, soil bulk density, and pH.
