In order to study the spatial characteristics of soil organic matter(SOM)in Daxing’an Mountains and further explore its influencing factors，181 representative soil samples were collected by using the five point sampling method with a sampling interval of 15 m×15 m.The attribute data and coordinate value of each point were obtained.Then，the distribution of SOM was preliminarily analyzed by ordinary Kriging methods and combined with the SOM prediction results from remote sensing image inversion.The results show that the variation coefficient of SOM content in Daxing’an Mountains is 76.95%，which belongs to medium degree variation； the near-infrared band 5 obtained by mathematical transformation of spectral reflectance data has significant correlation，with the highest correlation coefficient of -0.676； the next is red band 4，with the correlation coefficient of -0.508； the content of SOM is higher in the north and lower in the south，and the content in most mountain areas is higher.The spatial variation of SOM in the study area is affected by the factors of altitude，slope，slope direction and soil pH，among which altitude and soil pH are the main controlling factors.In the process of accumulation and consumption of SOM，topography factors and human activities may have a far-reaching impact.The research results can provide a reference for the sustainable development of soil resources，agricultural structure adjustment and large-scale prediction and analysis of SOM in Daxing’an Mountains.
