Abstract: Based on the meteorological data form 1961 to 2000,the Digital Elevation Model(DEM),terrain slope grid,image of TM,GPS orientation data and digital data for soil types,the precise comprehensive zonation for premature pear planting in Jinxi County of Jiangxi Province was made,combined with the environmental factors of the growth of the premature pear.The non-climate parameters,such as land use,soil types and slope were involved in the zonation.By using digital elevation model at 25m×25m grid,the zonation could be more precise to village and township level.The comprehensive review of different regions was made to provide references for the selection and optimization of the premature pear planting base.
