英文摘要：

Tannins,featureed by their phenolic structures, are widely used to prepare tannin resins. In this paper, the resources, structures and existed reactions during the synthesis of tannin resin were introduced. In addition, the research progresses of tannin resin in plywood, particleboard, wood preservation, impregna- ted decoration paper, structural glulam, fiber and others wood-based products, were reviewed. The main problems of tannin resin application and key research points for next step were put forward. The effective utilization of tannin in Chinese wood industry was prospected.
