中文摘要：

生物质资源的高值转化是研究热点。由于现有的生物质利用技术存在的技术单一，缺乏系统性理论指导等问题，导致原料利用率低，经济效益差，难以实现工业化生产，迫切需要建立新的理论体系。通过深入分析生物质转化过程中的共性问题，在综合多学科知识的基础上，提出了生物质科学与工程学这一理念，从生物质原料工程学，生物质转化过程工程学和生物质产品工程学三方面对生物质利用技术进行了全面、系统的研究，为生物质类可再生资源的高值化利用提供了新的研究思路。

英文摘要：

Many researchers have been dedicated to the utilization of biomass materials. It is, however, difficult for industrialization because of technological singleness and scare of system integration. And low utilization rate of materials and poor economic performance were got. A new perspective-biomass science and engineering-was put forward on the base of analyzing the intercommunity questions in biomass utilization and synthesizing multifold knowledge. Three parts, including biomass materials engineering, biomass transform process engineering and biomass product engineering were used for the comprehensive research of biomass utilization technology. Biomass science and engineering will be sure to develop new way for the high-value conversion ofbiomass resource.
