The subtropical hill region is the main area where the tea plantations are distributed in Chian, Trace elements are very important to tea quality, Study on the spatial variability of trace elements in tea plantation soils is the foundation of precision agriculture. With the original data as basis, the spatial variability of trace elements of montanic tea plantation soil in Mengshan is studied with the aid of principal component analysis and geostatistics model. The result showed: (1) The spatial variability of four trace elements(Fe, Mn, Zn, Cu) in tea plantation soils are similar. All of the theoretical model of trace elements are exponential model, the range of spatial correlation is 206~1 860 m. The spatial correlation of Fe, Mn, Zn belong to medium levels [C0/(C0+C): 25.1%~49.6％], the spatial variability between Mn and Cu similar anisotropic characteristic in NE111º, Fe and Zn trends to isotropy. (2) Principal component of comprehensive cartography describe the distribution rule of trace elements in general. Maps of Kriged estimates with principal component showed that the characters of trace elements distributed in a belt shape across the Mengshan mountain, which are in accordance with the result of geostatistic analysis. (3)The mainly influencing factors of tea plantation soil in Mengshan are soil condition and slope.
