The results showed that a total of 63 weed species belonging to 57 genera in 21 families were found in the major soybean producing regions of Inner Mongolia. The 21 families include Asteraceae family(nine genera and 14 species), Poaceae(11 genera and 11 species), Fabaceae(six genera and six species), and Polygonaceae(five genera and five species), Rosaceae(three genera and four species), Amaranthaceae(three genera and three species), Convolvulaceae(three genera and three species), Malvaceae(three genera and three species), Lamiaceae(two genera and two species), and the remaining 12 families including Plantaginaceae, Solanaceae, and Equisetaceae(each represented by one genus and one species). Amaranthus retroflexus, Chenopodium album and Echinochloa crus-galli showed relatively high abundance, making them the dominant weeds in the major soybean producing regions of Inner Mongolia. The Oroqen Autonomous Banner of Hulunbuir City exhibited the highest weed species richness, Simpson dominance, and Shannon-Wiener diversity indices, with values of 44, 0.918, and 3.030, respectively. The Songshan District of Chifeng City exhibited the highest Pielou evenness index of weed communities, at 0.846. The weed communities in the seven major soybean producing regions of Inner Mongolia could be classified into six groups. Among them, the weed community structures in Songshan District of Chifeng City and Horqin District of Tongliao City were clustered into one group with the highest similarity, while the weed community structures of remaining five major soybean producing regions each formed an independent group. keywords:Inner Mongolia  soybean field  weed  biodiversity  community structure  similarity  dominant species View Full Text  View/Add Comment  Download reader
