摘　　要：为明确鲅鱼圈口岸和盘锦口岸进境大豆携带杂草种子的物种组成与风险分析,采用相对多度分析、生态多样性分析、均匀度分析等手段综合分析了2021年进境大豆中携带的杂草种子。研究结果表明:不同来源国家的大豆携带杂草种子的物种组成、比例及群落多样性均存在较大差异,其风险程度依次为美国>巴西>阿根廷。To determine the species composition and risk analysis of weed seeds carried by imported soybeans at Bayuquan Port and Panjin Port,a comprehensive analysis of weed seeds carried by imported soybeans in 2021 was conducted by means of relative abundance analysis,ecological diversity analysis,evenness analysis,etc.The results showed that the species composition,proportion and community diversity of weed seeds carried by soybean from different countries were significantly different,and the risk degree was the United States>Brazil>Argentina.
