摘 要:以推广作物矮化品种为核心的“第一次绿色革命”被称为高投入的石油农业,它在给人类带来巨大利益的同时,也伴随着一些负面效应。世界人口的进一步增加和耕地、水资源不断减少所导致的未来巨大的食物供需矛盾,正引发以基因工程为核心的“第二次绿色革命”。由于发展与生态环境恶化的矛盾,我国必须采取有效措施,以同时保证“粮食供给”和“农业环境”双安全。The breeding and broad cultivation of semi-dwarf crop varieties in the 1960s and 1970s dramatically increased the grain production in the world, particularly in Asian countries, which was popularly recognized as the "First Green Revolution". Many factors have shown that the first green revolution has brought some environmental problems as well. The contradiction between the continuous increase of world population and the rapid decrease of farming land and water resources is calling forth a new green revolution marked with modem genetic engineering technology. To guaranty both the food security and environmental safety, the actions that China should take during the second green revolution were discussed.
