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: To determine the suitable planting area of Wenyujin in Wenzhou area and to expand its planting area in Wenzhou. Methods: Thirteen factors including climate and soil and environmental conditions were determined as the main factors affecting the growth of warm tulips according to the growth habit of warm tulip; the best producing sites were chosen as the target areas for similar introduction from Wenyujin Dao area; On the platform, the data of each site and sampling point are interpolated to each grid by inverse distance interpolation method, and the normalized 13 factors of gridding are eliminated to eliminate the influence of dimension. On this basis, calculate the absolute distance between each grid and the target point, and carry out cluster analysis according to the distance. The most suitable area, suitable area, sub-suitable area and unsuitable planting area were obtained in Wenzhou area. Results: Warm tulip was planted in most parts of Wenzhou. The most suitable area, suitable area and sub-suitable area accounted for 98% of the total area of Wenzhou and the most suitable area reached 62%. Conclusion: It is of great reference value to promote planting warm medicinal materials in Wenzhou.
