摘    要:综述了转基因作物对土壤生态系统影响的研究进展,包括转基因作物中的外源基因在土壤中的活性,转基因作物对土壤微生物区系有土壤酶活性的影响以及转基因作物对土壤动物区系的影响,转基因作物对土壤生态系统的影响与导入的外源基因特性和土壤类型相关,转基因产物进入土壤后引起的土壤生物变化的程度依赖于许多因素,最重要的决定因素是生态系统的复杂性和稳定性,评价不同转基因作物对土壤生态系统的影响具有重要的生态学意义,急需发展和完善以分子生物学为主的风险评价方法。

关 键 词:转基因作物  生态风险  评价  土壤生态系统  土壤微生物  土壤动物

Abstract:The effects of transgenic crops on the soil ecosystem were reviewed. The activity of Cry I Ab gene and proteinase inhibitor gene in the soil was summarized. The differences of soil microbes'components, soil enzyme activities, and soil fauna between genetic crops and isogenic strain crops were analyzed. According to current progress, the potential impacts of transgenic plant on soil microorganisms depend on the characteristics of the gene transferred into the crops and the soil properties. The change of soil ecosystem affected by many factors, and among them, the complex and stability of the ecosystem are the most important. The ecological effects of transgenic crops on the soil ecosystem need to be evaluated more fully before they are planted over extensive areas. Much effort should be devoted to the development of molecular techniques method to assess the effects of transgenic crops on soil ecosystem.
Keywords:Transgenic crops  Ecological risk assessment  Soil ecosystem  Soil microorganism  Soil fauna
