摘　　要：论述了转基因(GM)作物环境风险分析的概念、原则、参照物和研究进展。对基因漂流,GM作物是否会增加相关野生种的生存竞争性、入侵性和杂草性,是否会产生间接生态影响,是否会影响生物多样性,是否会产生“超级害虫”、“超级病害”,是否会通过基因的水平转移将转基因转至肠道和土壤微生物,以及GM作物的长期效应等问题进行了讨论。The concept, principal and base line for environmental risk assessment of GM crops and the progress made inrecent years are described. Will gene flow from GM crops to wild relatives increase competitiveness, invasiveness and weediness,will GM crops have potential indirect impact on ecosystem and diversity, will GM crops cause “superpests” and“superdiseases”, will transgene move into microorganisms resided in digestive track and soil through horizontal gene transfer,and finally the potential long-term impact of GM crops are discussed in detail.
