中文摘要:为调查转基因抗虫玉米种植对非靶标土壤动物群落结构的影响，以转cry1Ac基因抗虫玉米Bt-799及其对应的非转基因对照玉米郑58为试验材料，于2014—2015连续2年在东北黑土区采用手捡法和干漏斗法分别调查大型和中小型土壤动物的类群和数量，比较分析转基因与非转基因玉米田中土壤动物群落组成和多样性，并利用冗余分析（redundancy analysis，RDA）各环境因子在土壤动物群落结构形成中的作用。结果表明，郑58和转基因玉米Bt-799田中大型土壤动物总体群落组成相同，各类群多度无显著差异；2种玉米田间所有类群总体多度、物种丰富度、Simpson优势度指数、Shannon-Weiner多样性指数和Pielou均匀度指数均无显著差异，2014年其P值分别为0.949、0.867、0.751、0.998、0.985，2015年其P值分别为0.869、0.406、0.532、0.115、0.410；RDA分析表明玉米品种（系）在大型、中小型土壤动物群落结构形成中几乎没有作用。表明中短期内转基因玉米种植对非靶标土壤动物无显著影响。

Abstract:The transgenic insect-resistant maize with cry1Ac gene Bt-799 and its non-transgenic control Zheng 58 were selected to investigate the effects of transgenic insect-resistant maize on the community structure of non-target soil fauna. Hand picking and Macfadyen funnel methods were used to investigate the groups and individual numbers of macro, meso and micro soil fauna in the transgenic and non-transgenic maize fields, and the composition and diversity of soil faunas were compared in Bt-799 and Zheng 58 maize fields from 2014 to 2015. RDA analysis was also used to analyze the effects of soil environmental factors on soil community structure. The results showed that the composition of macro faunas was not significantly changed in transgenic Bt-799 compared with that in the non-transgenic maize; total abundance, species richness and community diversity index including Simpson index, ShannonWeiner index and Pielou index in Bt-799 were not significantly changed. The P values of total abundance, species richness and the three diversity indexes in 2014 were 0.949, 0.867, 0.751, 0.998 and 0.985, respectively, and the P values of those in 2015 were 0.869, 0.406, 0.532, 0.115 and 0.410, respectively. RDA analysis showed that the transgenic varieties had no effect on community structure of macro soil faunas, meso and micro soil faunas, suggesting that transgenic maize cultivation had no significant influence on community structure of soil faunas in the short and medium terms.
