摘要

Atractylodes is an East-Asiatic endemic genera that distributed in China, Japan and Russian Far Eastern. As an important resource of medicinal plant, atractylodes has long been used as herbal medicine. To example the significant features in its trueborn quality and geographical distribution, we explored the relationships between medicine quality and habitat suitability in two classifications–lower atractylodin content than the standard of Chinese Pharmacopoeia (2010) and the other has higher content. We found that the atractylodin content is negatively related to the habitat suitability for atractylodes with lower atractylodin, while the atractylodin content is positively related to the habitat suitability for those with higher atractylodin. By analyzing the distribution of atractylodeswith lower atractylodin content than the standard of Pharmacopeia, we discovered that the main ecological factors that could inhibit the accumulation of atractylodin were soil type (39.7%), soil clay content (26.7%), mean temperature in December (22.3%), Cation-exchange capacity (6%), etc. And these ecological factors promoted the accumulation of atractylodin for the atractylodes with higher atractylodin. By integrating the two classifications, we finally predicted the distribution of atractylodin content in China.Our results realized the query of atractylodes quality in arbitrary coordinates, and satisfied the actually cultivation demands of “Planting area based on atractylodin quality”.
