chinois. 摘 要：在田间试验条件下，采用直接观察法，通过对多样性指数、优势集中性指数、均匀性指数、物种数的分析比较，研究转基因耐草甘膦大豆对豆田节肢动物群落多样性的影响。结果显示，大豆生长期转基因耐草甘膦大豆和受体的节肢动物多样性指数、均匀性指数、物种数均显著低于当地常规品种，优势集中性指数显著高于当地常规品种，但转基因抗草甘膦大豆与对照受体间各指标无显著性差异，说明转基因耐草甘膦大豆对豆田节肢动物群落无明显影响。
Afficher plus [+] Moins [-]anglais. In natural fields, the effects of glyphosate tolerant soybean on Shannon-Winner diversity index, Simpson index, evenness and number of species were analyzed using direct observation method. The results showed that the Shannon-Winner diversity index, evenness and number of species of arthropods in glyphosate tolerant soybean fields and its receptor were significantly lower than those of the local conventional variety during the growing period. The Simpson index of arthropods in glyphosate tolerant soybean fields was significantly higher than that of the local conventional variety. There was no significant difference between glyphosate tolerant soybean and receptor. It was concluded that glyphosate tolerant soybean had no significant effects on arthropod communities in soybean fields.
