摘　　要：转基因大豆对田间节肢生物多样性的影响是转基因生物生态安全性评价的重要组成部分。采用直接观察法对3种转基因大豆及其非转基因受体的田间节肢动物进行调查,分析了大豆田节肢动物群落的功能群、丰富度指数、Shannon-Wiener多样性指数、Pielou均匀度指数、优势集中性指数随时间的变化规律,并比较了其差异。结果显示,种植在不同试验地点的不同品种转基因大豆的各类多样性指数变化趋势稍有不同,但不同转基因大豆与非转基因对照相比,主要功能团组成数量及其丰富度、多样性、均匀度、优势集中性指数间均无显著差异,各类指数随时间变化的动态趋于一致。综合分析表明,3种抗除草剂转基因大豆的种植对大豆田间节肢动物无显著影响,这为转基因大豆的生态安全性评价提供了数据支持。The effect of transgenic soybean on arthropod biodiversity in the field is an important part of biosafety assessment.Arthropods in the fields of three transgenic soybean varieties and their non-GM counterparts were investigated with direct observation,and the functional groups in the arthropod communities,richness index,Shannon-Wiener diversity index,Pielou evenness index,and dominant concentration index were analyzed,and the differences were then compared.The results show that although the trends of those indexes of different transgenic varieties and their counterparts were slightly different,but there were no significant differences in the above indexes between transgenic soybean and the control.The dynamics of various indexes of arthropods in GM soybean fields and its non-GM control showed similar tendencies over time.It was suggested that GM soybean had no significant effects on arthropods in the fields,which provides data to support the biosafety assessment of transgenic soybeans.
