摘要
利用1961-2000年气象站观测资料、数字高程模型(DEM)及坡度图、TM卫星影像、GPS定位及数字化土壤类型数据,结合早梨生长的生态环境指标对江西省金溪县早梨种植进行了精细化综合区划;与单纯考虑气候因素相比,土地利用、土壤、坡度等非气候因素的考虑,使区划结果在反映气候适应性的基础上,进一步反映了早梨可种植的土地利用现状、适宜种植坡度和土壤类型;25m×25m分辨率DEM的使用,使区划结果细化到乡村级;不同区域的面积计算、分区域特点的综合评述,可为早梨种植基地选择、优化布局、防灾减灾提供重要参考。
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.
