基于GIS的地道药材温郁金种植适宜性评价

Suitability evaluation to planting area of Curcuma wenyujin based on GIS

根据生物引种的相似性原理,以温郁金地道产区环境因子为目标值,应用G IS技术分析温郁金适宜种植区,为温郁金科学引种栽培提供依据。结果表明:温郁金在温州具有广泛的适宜种植区,其中最适宜面积占全市行政面积的61.93%,适宜面积占24.93%,一般适宜面积则为10.61%;以瑞安、瓯海、龙湾、鹿城、永嘉组成的区域带为最适宜种植分布中心。研究结果与古代及现代文献记载的温郁金产地具有很好的相似性,并与近几年温郁金推广种植工作相吻合。

To provide a scientific basis for introduction culture of Curcuma wenyujin,the GIS was used to analyze the adaptive planting area based on the optimum ecological factors of Curcuma wenyujin according to the theory of organism introduction.The results showed there were wide adaptive planting areas in Wenzhou Region,the best adaptive planting areas accounted for 61.93% of the total region area,the proportion of adaptive planting areas was 24.93%,while the proportion of ordinary adaptive planting areas was 10.61%.The centre zone of adaptive planting areas was made up by five places including Rui＇an,Ouhai,Rongwan,Lucheng,Yongjia.The results obtained by GIS analysis were corresponding to the records in ancient and modern literature,which was conformed to the practical work of planting extension during recent years.
