摘要
为了解常山(Dichroa febrifuga Lour.)现有产区分布并预测新的产区,本文利用中药材产地适宜性分析地理信息系统TCMGIS(Geographic Information System for Traditional Chinese Medicine)对426个常山样品信息进行了适宜生态因子生长范围确认,分析了常山适宜产地空间分布状况。结果显示,常山主要分布于我国温暖湿润的东部季风区,生态相似系数100%区域分布较为集中,总面积达760 640.1 km2,共829个县区,其中广西、云南、广东、湖南分布较多。本研究结果对常山的野生资源保护、人工规范化种植和资源可持续利用具有重要意义。
To define the regional distribution and predict new areas of Dichroa febrifuga Lour.,we determined distribution areas and ranges from 426 samples using the Geographic Information System for Traditional Chinese Medicine（ TCMGIS）. Analysis showed that D.febrifuga was mainly distributed in the East Monsoon Area of China. A total of 829 counties in14 provinces,covering a land area of 760 640.1,shared similar ecological factors with those of native habitats appropriate for D. febrifuga. The four provinces with the largest areas were Yunnan,Guangxi,Guangdong and Hunan. This study will be of benefit for the conservation planning of wild resources,artificial cultivation and sustainable utilization.
