Abstract: By using correlation analysis, canonical correspondence analysis (CCA), and two way indicative species analysis (TWINSPAN), this paper analyzed the relationships of Arctium lappa community distribution and species composition with eco environmental factors. No significant correlations were observed between the importance value of  A. lappa and eco-environmental factors, suggesting that A. lappa was a idespread specie. The distribution of accompanying species in A. lappa community was positively correlated with relative air humidity, mean annual precipitation, mean annual temperature, and altitude, and negatively correlated with soil organic matter content and sunshine hours. The
A. lappa community was zoned into four main production areas, i.e., Northeast China, Northwest China, Southwest China, and Southeastern coastal area, which was consistent with the records in the Chinese Medical Code.
