中文摘要：

目前国内外所开发的木质素产品已经有数百种，但是，由于木质素本身结构非常复杂且木质素的种类繁多，使得开发木质素产品存在一定的盲目性。如何有效地利用木质素的结构特性来控制已有木质素产品的性能稳定性、开发更多性能优良的木质素产品以及实现木质素高附加值产品生产的规模化、产业化等，将成为木质索研究的一个重要方面。文章结合近年来木质素产品的研究及开发，介绍了木质素结构与功能之间的联系，以期能够充分利用木质素的结构特点来改进和生产木质素产品。

英文摘要：

Hundreds kinds of lignin-based production have been produced inside and outside of China. However, the complicate structure and plentiful resource result in certain blindness of lignin exploitation. How to use the structural character of lignin to efficiently control the stable performance of existing lignin-based products, to explore more and more excellent lignin-base products and finally to realize the industrialized and large-scale production will become the key problems. This essay combine the study and explore of existing lignin-base products, introduced the relationship between the structure and function of lignin, expect it could provide some help to extent the higher appending value utilization oflignin.
