基于数码相机获取的土壤照片，利用 photoshop 软件提取相片 RGB 值，分析土壤有机质含量与颜色的量化关系。结果表明，土壤有机质含量与 RGB 值存在明显的负相关线性关系，其中有机质含量与 RGB 中 G 值关系最为显著。通过分析林地0～50 cm 不同深度土壤发现，有机质含量整体出现w（10 cm）＞ w（20 cm）＞ w（30 cm）≈w（40 cm）＞ w（50 cm）层，而土壤亮度值表层低于底层。

In this study,soil photos were taken by digital camera and the RGB value of the photo was extracted using the image processing software of photoshop.The relationship between the soil organic matter and the RGB values of each soil were ana-lyzed.The results showed that the soil organic matter and the RGB value of soils were negatively correlated,among which the correlation coefficient of soil organic matter and theG value were dominant.Meanwhile,the contents of soil organic matter below 0 to 50 cm soil depth were also analyzed,indicating that the contents of soil organic matter werew(10 cm)> w(20 cm)> w(30 cm)≈w(40 cm)>w(50 cm),while the values of soil brightness of the upper soil layer was lower than that of the deeper soil layer.
