Spatial Variability Analysis of Reclaimed Wetland Soil Nutrients in Sanjiang Plain, China

摘要

Based on the measured sample data, geostatistics and geographic information system were utilized to analyze the spatial variability of six soil nutrients variables of reclaimed wetland in Sanjiang Plain. All soil nutrients studied had spatial autocorrelation in some extent, and kriging could successfully interpolate these variables. Thus, the combined method could accurately evaluate the spatial variability of soil nutrients in study area.
