Spatial Pattern and Influence Factor Analysis of Soil Organic Matter Based on the GeoDetector Model: Taking Liaoyang—Anshan Area as an Example

Spatial pattern of organic matter distribution and its influencing factors in the study area can provide a decision-making basis for territorial spatial planning. The majority of previous studies in this area focused on the soil surface, and most of them studied the influence of single factors. Therefore, the characteristics, spatial pattern and multi-factor influence of soil horizontal and vertical organic matter content were studied. The results showed that organic matter was higher in the southeast and lower in the northwest, and decreased with increasing depth. Organic matter was positively correlated with total nitrogen, total phosphorus, viscosity and silt content, and negatively correlated with sand content and bulk density. The interaction of any two factors was greater than that of a single factor. The BRIEF REPORT is available for this paper at http://www.ykcs.ac.cn/en/article/doi/10.15898/j.ykcs.202412050251.
