摘要:通過人類社會的發展進步,可以看出能源已經成為了主要驅使發展的動力。同時能源也是一個國家經濟和社會發展的重要基礎,是世界各國戰略安全的重要組成部分。但是目前世界上使用最多的是石油、煤炭、天然氣等這一類的不可再生的石化能源。這類石化能源雖然快速有效的推動了人類社會的發展進不,可同時也造成了空氣污染、全球變暖等危害地球生態環境的影響。而且更具預測石油等石化資源的全球儲量已經不足以支持人類以目前消耗水平的使用,比如有人預測目前探明的石油儲量只夠人類再使用20年,所以當務之急是尋找到可以再生的能源繼續供給人類使用。
生物能源作為可再生能源和綠色能源,已經受到廣泛的關注,國內外對于其展開了大量研究。雜交狼尾草是近年來發展十分迅速的高產牧草,柳枝稷是北美地區生命力旺盛的一種草本能源植物。這5種植物都具有成為能源植物提供大量生物質能源的潛力,因而對5者的生理特性進行比較期望可以篩選出一種較為優秀的能源植物。不僅可以為能源植物的選擇提供更好的選擇,也可以為利用一些不適合傳統農業生產的邊際土地提供方法。36577
本課題是主要觀察研究雜交狼尾草、柳枝稷、矮蒲葦、蘆竹、特萊茵狼尾草,這五種能源植物的生長狀況。這五種能源植物近年來受到越來越多的關注,本研究依托地處奉賢濱海鹽堿地區,開展一些列對于這5種能源植物生理特性研究,以了解這些植物在當地的物候表現

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 源¥自%六^^維*論-文+網=www.aftnzs.live
