经济社会的发展以能源为重要能力,大力开发和利用新能源之一的生物质能源,对于缓解21世纪的能源、环境和生态问题具有重要意义,产生诸多利益。生物质能是由植物的光合作用固定于地球上的太阳能,最有可能成为21世纪主要的新能源之一。据估计,植物每年贮存的能量约相当于世界主要燃料消耗的10倍;而作为能源的利用量还不到其总量的l%。 Economic and Social Development Energy-based biomass energy, one of the major sources of new energy development and utilization, is of great importance and has many benefits for alleviating the energy, environment and ecological problems in the 21st century. Biomass is solar energy that is fixed to the earth by the photosynthesis of plants and is most likely to become one of the major new sources of energy in the 21st century. It is estimated that plants store about 10 times the annual energy consumption of major fuels in the world and less than 1% of their total energy use.
