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.
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.
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.
This result give important reference value of Curcuma wenyujin breeding in Wenzhou.
根据温郁金的生长特性，确定温州地区温郁金的适宜种植区域，扩大其种植范围。
选取气候、土壤等13个主要环境因子，以最佳道地产区为目标区域进行相似性计算，利用地理信息系统（GIS）的反距离权重插值法对站点及采样点数据进行网格化处理，去除网格化数据的量纲效应，在此基础上计算每个像元到目标像元的绝对距离，通过聚类分析将温州地区划分为最适宜区、适宜区、次适宜区和不适宜区。
温州地区大部分区域适合温郁金生长，最适宜区、适宜区、次适宜区和不适宜区面积占温州地区总面积的98%。
该研究结果对温州地区温郁金种植具有重要的参考价值。
