| 摘要：通过人类社会的发展进步，可以看出能源已经成为了主要驱使发展的动力。同时能源也是一个国家经济和社会发展的重要基础，是世界各国战略安全的重要组成部分。但是目前世界上使用最多的是石油、煤炭、天然气等这一类的不可再生的石化能源。这类石化能源虽然快速有效的推动了人类社会的发展进不，可同时也造成了空气污染、全球变暖等危害地球生态环境的影响。而且更具预测石油等石化资源的全球储量已经不足以支持人类以目前消耗水平的使用，比如有人预测目前探明的石油储量只够人类再使用20年，所以当务之急是寻找到可以再生的能源继续供给人类使用。 生物能源作为可再生能源和绿色能源，已经受到广泛的关注，国内外对于其展开了大量研究。杂交狼尾草是近年来发展十分迅速的高产牧草，柳枝稷是北美地区生命力旺盛的一种草本能源植物。这5种植物都具有成为能源植物提供大量生物质能源的潜力，因而对5者的生理特性进行比较期望可以筛选出一种较为优秀的能源植物。不仅可以为能源植物的选择提供更好的选择，也可以为利用一些不适合传统农业生产的边际土地提供方法。36577 本课题是主要观察研究杂交狼尾草、柳枝稷、矮蒲苇、芦竹、特莱茵狼尾草,这五种能源植物的生长状况。这五种能源植物近年来受到越来越多的关注，本研究依托地处奉贤滨海盐碱地区，开展一些列对于这5种能源植物生理特性研究，以了解这些植物在当地的物候表现 毕业论文关键词： 能源草；柳枝稷；杂交狼尾草；矮蒲苇；芦竹；特莱茵狼尾草 Several observational studies energy grass phenology and growth Fengxian area Abstract: With the development and progress of human society, energy has become an important force driving growth. At the same time energy is also an important basis for national economic and social development is an important part of the strategic security of the world. [1] However, the use of the world's more mature energy - mostly oil, coal and natural gas and other non-renewable energy sources. Although fossil fuels such strong impetus to the development of human society, but also had an impact on the global environment harmful air pollution, global warming. And more predictable oil and other fossil resources have been insufficient to support the global reserves at current consumption levels of human use, such as it was predicted current proven oil reserves enough for 20 years before humans, so look for renewable energy sources has become a top priority . Bio-energy as a renewable energy and green energy, has received widespread attention at home and abroad to expand a lot of research. Pennisetum is developing very rapidly in recent years, high-yield grass, switchgrass is North America's great vitality and a herbaceous energy plants. The five plants have become a source of biomass energy plants provide a lot of potential, so the physiological characteristics were compared 5 persons expect to filter out a more excellent energy plants. Not only can provide better choice selection of plants for energy, but also for the use of some marginal land not suitable method of providing traditional agricultural production. The project main five kinds of energy plants in Hybrid, switchgrass, dwarf pampas grass, Arundo donax, Terai Yin Pennisetum, these five plants are more and more attention in recent years, this study relies on Coastal Saline is located in Fengxian area, to carry out a series for the study of physiological characteristics of these five kinds of energy plants to see how these plants was at a local phenology KeyWords：Energy grasses; switchgrass; Pennisetum; dwarf pampas; Arundo donax; Terai Inn Pennisetum 目录 1 绪论1 1.1 能源草的特性与利用 1 1.1.1 能源草的特性1 (责任编辑：qin) |
