SOC Content at Different Soil Depths in the Study Area. (5–10 cm). Note: a represents Mangui; b represents Hanma; c represents Genhe Plantation Forest; d represents Genhe Natural Forest. The colors represent the relative levels of SOC content in each plot: yellow indicates low SOC content, green indicates medium SOC content, and blue indicates high SOC content. The variation in color intensity further reflects the level of organic carbon content, with darker colors indicating higher organic carbon content in each plot.
