中文摘要：
【目的】 转基因玉米种植在吉林已经开展环境释放试验，但是对土壤动物影响并不清楚。【方法】本文通过一年野外实验，研究了转植酸酶玉米田间种植对土壤跳虫的影响。【结果】 研究结果发现，转植酸酶玉米种植对跳虫多度、类群丰富度、群落多样性指数及群落结构均未产生显著影响。但是可以使其中一些稀有类群消失。而不同的玉米生长期显著影响了跳虫的群落结构。同时玉米生长期也显著影响了跳虫的多度，跳虫多度在玉米成熟期最高。这可能与玉米凋落物对跳虫的食物供应有关。【结论】 转植酸酶玉米C63-1田间种植一年，对跳虫并未产生显著影响，但是未来还需要进行长期野外监测试验和室内控制实验最终确定转基因玉米的环境安全性。
英文摘要：
[Objectives] To investigate the effect of an experimental release of transgenic corn in JilinProvinceon soil fauna. [Methods] Field experiments including two corn varieties (transgenic corn C63-1 and its Control) were conducted to investigate the effects of transgenic corn on soil Collembola in 2012. [Results] Our results showed that density, species richness, diversity and community structure were not impacted by transgenic corn cultivation but some rare species disappeared in transgenic corn plots. Collembola community structure was significantly affected by different corn growth periods; Density of Collembola was highest in the mature corn stage, possibly because of abundant corn litter (a food resource of Collembola) during that growth stage. [Conclusion] Transgenic corn cultivation did not have a significant effect on soil Collembola over the course of a one year experiment. However, longer-term, controlled experiments should be done to ascertain the environmental safety of transgenic corn cultivation.
