Spatial distribution characteristics and spatial relationships of land use are important contents in land use planning.In current research, traditional qualitative analysis method is usually adopted, but quantitative analysis method is rarely used.Based on land use types classification, this paper proposed a spatial autocorrelation index named auto-adjacency to quantitatively analyze spatial autocorrelation of nominal variables, and used Visual Studio platform to realize the algorithms implementation.In the end, this research set Changping District of Beijing as an example.Results showed that the method could quantitatively measure spatial autocorrelation, and characterize spatial distribution and spatial relations of land use.
