| 摘 要： | 生物质能源生产是能源发展领域的重大挑战,在解决新的替代能源中扮演着重要角色。本文着重论述了美国生物能源生产的生态环境问题。从经济、环境和战略方面考虑,生物能源有望提高国家安全,因而受政策驱动的美国生物能源生产技术备受注目。尽管生物能源具有诸多潜在效益,但是在北美,生物原料供应、高强度经营的土地上农药使用及其对陆地野生动物的潜在影响等令人担忧,我们分析了其中的原因。通常认为,未来生物能源的环境、经济效应是正面的;然而,谨慎地审视和发展生物能源经济以保护生态系统的可持续性显得至关重要。

| Abstract: | This paper focuses on the eco-environmental aspects of U.S. biofuel production, a grand energy challenge with an important role in addressing new alternative energy sources. Policy driven approaches have made U.S. biofuels attractive for economic, environmental and strategic reasons with a potential to improve national security issues. Despite the many potential benefits of biofuels we will examine causes for concerns relating to biofeedstock supplies, agro-chemical usage on intensively managed landscapes and potential impacts to terrestrial wildlife in North America. The environmental and economic effects of future biofuels are generally perceived as positive; nonetheless, it will be critical to peruse and develop a biofuels economy with caution to safeguard systems sustainability. |
