%X Moran's I statistics was applied to describe the spatial autocorrelation coefficients,correlation distance and spatial pattern of heavy metals in cultivated soils in Beijing.Significant spatial autocorrelations were detected for 8 heavy metals and the autocorrelation distances were:Cr,57;Ni,75;Zn,57;Hg,55;Cu,55;Pb,65;As,74 km;and Cd,37 km.Local Moran's I was used to analyze the spatial distribution pattern of the heavy metals and identify the spatial clusters and spatial outliers.Taking Cr and Hg as example...
