摘　　要：道地中药材是指经过中医临床长期应用优选出来的,产在特定地域,与其他地区所产同种中药材相比,品质和疗效更好,且质量稳定,具有较高知名度的中药材。甘肃省得天独厚的自然气候条件孕育了中医临床应用广泛的甘肃道地中药材当归,区域间生态环境的相似性造就了众多优质当归产区。基于不同产区当归空间分布数据及酚酸类成分含量,从中药道地性研究“优质(独特化学型)”的角度出发,采用ArcGIS地理信息系统部署下的空间数据统计分析方法对道地产区、新兴产区、新兴种植区当归酚酸类成分总含量进行空间相关性与差异性分析,并应用地理探测器分析模型进一步探析了当归酚酸类成分总含量在地理空间中的分布规律及主要驱动因子,为当归道地性研究及生产区划提供依据。Dao-di herbs,produced in a specific region and screened through long-term clinical application,is characterized by high stable quality,good efficacy,and high popularity.With favorable climate conditions,Gansu gives birth to the Dao-di herbs Angelicae Sinensis Radix which is widely used in clinical practice,and multiple regions in Gansu,with similar ecological environment produce Angelicae Sinensis Radix.In this study,the spatial correlation and difference of phenolic acid content in Angelicae Sinensis Radix from Dao-di producing areas,emerging producing areas,and emerging planting areas in Gansu were analyzed based on ArcGIS to explore the"quality(chemical type)"characteristics of genuine Angelicae Sinensis Radix.Moreover,spatial distribution law and main driving factors of the total phenolic acid content in Angelicae Sinensis Radix in Gansu were analyzed based on geodetecctor.This study is expected to lay a basis for Dao-di research and production regionalization of Angelicae Sinensis Radix.
