中文摘要：中国是目前唯一一个将转基因树种商业化的国家，这引起了全世界的关注。转基因杨树作为一种多年生树种，具有较长的生长周期，需要进行长期的生态风险试验。本研究旨在探讨多年生转基因杨树在节肢动物群落、土壤理化性质、基因流、土壤微生物多样性等方面的生态安全性。研究发现，转基因杨树能有效抑制害虫数量。转基因741杨对节肢动物群落的稳定性没有影响。杨树微生物多样性研究表明，转基因杨树不影响土壤理化性质和土壤微生物群落结构。此外，微生物群落结构明显受地点和季节的影响。研究结果表明，5年生转基因741杨不会带来生态风险，不影响微生物群落结构或功能多样性。本研究为转基因杨树的生态安全评价提供了参考，为促进转基因杨树商品化提供了理论依据。
外文摘要：China is currently the only country that has commercialized genetically engineered tree species, and this has attracted worldwide attention. As a perennial tree species, transgenic poplar has a long growth cycle and needs to be tested for long-term ecological risks. The main purpose of this study was to explore the ecological safety of perennial transgenic poplars in arthropod community, physical and chemical properties of soil, gene flow, and soil microbial diversity. The study found transgenic poplars could effectively inhibit the number of pests. Moreover, transgenic poplar 741 did not affect the stability of the arthropod community. Studies on the microbial diversity of poplar showed that transgenic poplars did not affect the physical and chemical properties of the soil and the soil microbial community structure. Furthermore, the microbial community structure was obviously affected by location and season. The results showed that a 5-year-old transgenic 741 poplar did not pose an ecological risk, and did not affect the microbial community structure or functional diversity. This study provides a reference for the ecological security evaluation of transgenic poplars, and provides a theoretical basis for promoting the commercialization of transgenic poplars.
