The invention aims at providing a fine partition method of soil pollutant content spatial distribution. The fine partition method of the soil pollutant content spatial distribution solves the problem that an existing spatial interpolation method cannot achieve fine partition of soil pollutant distribution due to the problem of interpolation transboundary. The fine partition method uses a spatial relation between the soil pollutant content distribution and a pollution source as a reference, extracts a constraint region, builds a boundary constraint space interpolation algorithm based on the constraint region, enables spatial interpolation to be restrained in a reliable space region, and achieves the fine partition of the soil pollutant content distribution. The fine partition method of the soil pollutant content spatial distribution has the advantages of extracting the pollution source influence range serving as a boundary constraint condition, restraining spatial interpolation of unknown sites in the reliable space region, and achieving accuracy and reliability of partition of the soil pollutant content distribution. The fine partition method of the soil pollutant content spatial distribution is suitable for digital map production of the pollutant content distribution of the fields of soil, zoology, hydrology and the like.
