Abstract:Spatial heterogeneity of total carbon content, available nitrogen, phosphorus and potassium content in thin layer black soil of Shuangcheng city, Heilongjiang province was analyzed by geostatistics method. The results showed all of them had heterogeneity. Soil total carbon content was significantly impacted by spatial distance, the depth of black soil layer affected its spatial distribution. There was a relative low spatial heterogeneity of available nitrogen, phosphorus and potassium content, more than 80 percent of them was affected by stochastic factors. The range of total carbon content, available nitrogen, phosphorus and potassium content was 15.7 km,4.6 km,11.2 km,7.1 km, respectively. There were significant correlation between total C and available N.
