摘　　要：在田间自然条件下,用直接观察法和吸虫器研究了抗草甘膦转基因大豆对豆田节肢动物群落的影响。结果表明,种植抗除草剂转基因大豆的豆田节肢动物群落和非转基因亲本大豆豆田节肢动物群落的物种数,优势集中性指数、多样性指数相似程度较高,它们之间差异不显著,说明抗除草剂转基因大豆对节肢动物群落多样性无明显影响。Effects of herbicide tolerant soybean on biodiversity of non-target arthropods communities were evaluated and conducted in the soybean field using direction observation and vacuum-suction machine methods in 2005 in Hebei, China. The resuhs showed that there were no significant difference between herbicide tolerant soybean and non-transgenic soybean in Shannon-winner diversity index, simpson, evenness, number of species and dominant concentration of arthropod communities. This resuhs indicated the herbicide tolerance soybean has no significatence impact on biodiversity of arthropods populations.
