转基因作物对生态环境的潜在风险

Potential risk of genetically modified crops to ecological environment

转基因作物在全球范围内的广泛应用在带给人类巨大利益的同时,也可能产生一系列风险。该文概述了转基因作物对生态环境的潜在风险,针对转基因作物的杂草化问题,分析了产生杂草化的遗传和环境因素,同时阐述了转基因作物的释放对生物多样性及生态系统的影响。

Genetically modified crops （GMC） have been cropped on large scale so far in many countries, which plays a great role in creating economic benefits. While at the same time, an increasing attention had also been paid for the risks brought about by the release of GMC. In this paper, the environmental impacts of GMC were reviewed. Aiming at the problem of GMC weediness were reviewed, its genetic and environmental factors were analyzed. At the same time, the effects of GMC on biodiversity and ecosystem were elaborated.
