中文摘要：

木质纤维素生物质高值化利用的主要途径是当前的生物质炼制及多级资源化利用模式，即生物质各组分分别转化为材料或化学品，最终实现生物质组分的高值化利用。概述了当前生物质转化为材料和化学品的主要思路，即基于“生物质原始结构解译-组分选择分离-分离组分的结构解析及高值转化”的模式，该模式对于木质纤维素资源高效利用具有重要的指导意义。

英文摘要：

The main route for value-added utilization of lignocellulosic biomass is the current pattern of biorefining and multi-level resource utilization,in which all the individual components of biomass are converted into materials or chemicals,resulting in fi nal value-added applications of biomass.This paper summarizes the main route for the conversion of biomass into materials and chemicals.This route is based on the procedures of'structural analysis of structural features of native components-selective separation of component-structural analysis of the isolated components and their valueadded applications',which has an important guiding signifi cance for the multistage utilization and value-added applications of lignocellulosic biomass.
