Geo-statistics combined with classical statistics were applied to analyze the spatial distribution of soil nitrogen( N) and phosphorus( P) content under three different land uses in Chahe watershed at the lower Yangtze River. The results showed that soil N and P content distribution varied significantly in paddy,upland,and vacant land,while the coefficient of variation also varied greatly among the three land uses. All spatial distributions of N and P content values were anisotropic and directions of most l...
