摘　　要：目的:确定温郁金在温州地区的适宜种植区域,扩大其在温州的种植范围。方法:根据温郁金生长习性,确定出包括气候和土壤及环境条件的13个因子作为影响温郁金生长的主要因子;从温郁金的道地产区选择生产最好的地点作为引种相似计算的目标区;在ArcGIS平台上将各站点和取样点的数据通过反距离插值法插值到各网格,对网格化的13个因子进行归一化处理,消除量纲的影响。在此基础上,计算各网格与目标点的绝对距离,根据距离的大小进行聚类分析。得出温州地区的温郁金种植最适宜区、适宜区、次适宜区及不适宜种植区。结果:在温州地区绝大多数地方都可以种植温郁金,最适宜区、适宜区、次适宜区占温州总面积的98%,最适宜区也达到62%。结论:对温州地区推广种植道地药材温郁金具有重要的参考价值。Objective：This stdudy was to determine the suitable area for Curcuma wenyujin in Wenzhou,and expand its growing region,based the growth characteristic of Curcuma wenyujin.Methods：The 13 main factors including climate,soil and other environmental conditions were selected.The best genuine production area was regarded as the goal area in similar calculation.The grid data was calculated from the station and sampling sites by Inverse Distance Interpolation on GIS.After normolizing to the grid data,the dimension effect was removed.on this basis,calculating the absolute distance of every cell to the the goal cell.Wenzhou region was divided into best suitable area,suitable area,second suitable area and unsuitable area by clustering analyzing.Result： Most of area in Wenzhou are suit for Curcuma wenyujin,best suitable area,suitable area,second suitable area and unsuitable area reach 98% area of Wenzhou.Conclusion： This result give important reference value of Curcuma wenyujin breeding in Wenzhou.
