卷首语
生物质能生生不息
我们现在所说的生物质能从广义上说属于太阳能，是太阳辑射经植物的光合作用面幕能于生物质，以此为载体的一种化学态能量。生物质能应该是人类最古老的能源利用方式，所谓"钻木取火"就是远古人类发现和使用生物质能的一种原始方式，人类由此加快了进化的步伐。千百年来草原上的牧民使用牛羊类烧火做饭，可以说是开创了生物资源循环利用的先河。牧草秸秆首先给牛羊提供了必需的养分和能量，经过牛羊体内一系列生化过程将废弃物排出，牧民将其晒干后又成了很好的燃料，再一次为人类生活提供了能量，实在是物尽其用。
生物质能源远流长，现代科技的发展又为我们展示了更加广阔的空间。生物质能原料易得，既可以是农产品，如玉米、高染、薯类及水生植物等：也可以是度弃物，如秸秆、菌渣、林木枝梗、畜禽粪便以及城市垃圾等。生物质能的现代加工转化技术与途径多样，既可以直接燃烧发热或者发电，又可以转化为固态、液态、气态多种形态。光电受光照时间和强度制约、风电受风力变化影响，而生物质能来源则更加丰富可靠，能量更加便于大量储存和调配
VolumePreface
使用。
地球每年经光合作用产生的物质有1730亿吨.其中蕴含的能量相当于全世界能源消耗总量的10~20倍，但目前的利用率不到3%。中国的生物质能具有得天独厚的资源优势，有报告显示，中国的生物质能源的资源量是水能的2倍，风能的3.5倍。中国每年白白烧掉的秸秆就有 1亿吨以上，如果用来发电可相当于两个三峡电站。城市生活垃圾中有1/3以上的有机物，如能充分利用可有效缓解‘垃圾围城'造成的土地资源紧缺和环境污染。
“离离原上草，一岁一枯荣。野火烧不尽，春风吹又生”，唐代诗人白居易旱在一千多年前就为我们描绘出了生物质能取之不尽用之不竭的美好前景。生物质能源远流长生生不息，作为一种古老而又新型的能源形式，现代科技为它的深度开发和使用开辟了非常广阔的空间，我们有理由相信，生物质能源将为我国的经济建设和能源安全做出更大的贡献，也将为人类贡献一个更加友善和可持续发展的生存空间。

BiomassEnergyContinueEndlessly
Broadly speaking, is part of solar energy. Solar radi-ation storages energy in biomass through photosynthesis and is a chemical state energy taking biomass as a carrier. Biomass is human's oldest way of energy use. The so-called " make a fire by drilling wood" is a primitive way for ancient human discoverying and using biomass energy, thus human accelerated the pace of evolution. For thou-sands of years,Herdsmen on the grassland use cow and sheep dung for cooking, which create a precedent for the recycling use of biological resources. Firstly, grass straw provide cow and sheep with necessary nutrients and ener-gy, cow and sheep discharge waste through a series of bio-chemical processes in vivo, then herdsmen dry the waste that became good fuel, which provides the energy of hu-manlife.
Biomass energy has a very long history and modern technology development also shows us its broader space.
Raw materials of biomass energy are easy to get, they may be com, sorghum, potato, and aquatic plants, but also may be waste, such as straw, bagasse, tree branches, an-imal manure and urban waste, etc.. Biomass conversion technology and modern processing has many ways, which can heat or generate power by direct combustion, but can also be transformed into variety of forms such as solid, liq uid，gaseous.
China's biomsss energy resources are tremendous, which can effectively alleviate the shortage of land re-sources and environmental pollution.
We have reason to believe that Biomass will make greater contributions to China's economic construction and energy security, provide us a more friendly and sustain-able living space.
