Abstract：In order to reveal the spatial variability and influencing factors of soil organic matter,the reference for the analysis and evaluation of soil fertility is provided in a mine-grain complex area,it is used GIS technology and goestatistics to research the spatial variability and influencing factors of soil organic matter,and the three-dimensional landscape map is built through using the DEM of Xinzheng City.The results showed that the soil organic matter of Xinzheng had moderate spatial variability and spatial correlation,the spatial variability was caused by the natural and human factor.The three-dimensional landscape map of soil organic matter could intuitively reflect the relationship between the spatial distribution of organic matter and the geographical environment.
