The Spatial Heterogeneity Analysis of Soil Salinity at Coastal Reclamation Area in Wenling
Based on a combinat ion of classical statistics and geostatistics method,this thesis studied spatial heterogeneity of soil salinity in coastal reclamation area in Wenling,Zhejiang Province at three different scales (1800 m × 800 m,600 m × 420 m and 300 m × 300 m).The study results indicated that the soil salinity at three different scales was lognormal distribution and exhibited moderate spatial variability.Semi-variance was in line with exponential model,with strong spatial correlation.Moran's I coefficient showed that spatial correlation of soil salinity at the small scale (S) was weak,while spatial correlation of soil salinity at the middle (M) and Large scale (L) were comparatively high.Kriging interpolation and correlation analysis accurately showed the spatial distribution and the variance tendency.On the basis of this analysis,this thesis aimed to find out the spatial variability law of soil salinity and provide the theoretical basis and practical experience for the management,improvement and utilization of the salinized coastal reclamation area.
