Aiming at the deterioration of soil physico-chemical properties due to the improper exploitation and utilization of soil resources in the coastal region, spatial heterogeneity of soil physical property of surface bulk density was analyzed by using geostatistical method, which was performed in coastal reclamation region of north Jiangsu Province. The results indicated that surface soil showed a compaction trend, and the variation of bulk density under various vegetation types was rather weak. Surface soil bulk density generally exhibited isotropy and exponential model was fitted to its semivariogram. Bulk density exhibited moderate spatial autocorrelation owing to compound impact of structural and stochastic factors. Moran’s I coefficient analysis proved that bulk density showed weak spatial dependency, and stochastic factors were the crucial reason of the spatial heterogeneity. Bulk density in rice field was significantly higher than that in cotton field, and the spatial distribution of bulk density was related to differences in both land use patterns and soil textures. The research results can serve as a theoretical reference to the rational utilization and scientific management of moderate-and-low-yield farmlands and obstacle soils in coastal region.
