随着工业发展和人口的增加,近几年来,世界各国木材需要量不断增加,而木材的采伐量和生长量则落后于需要量的增长。为解决木材的供需矛盾,许多国家除了扩大森林资源和提高木材综合利用率外,还积极创制合成木材。例如在日本,合成木材的研究已被列入国家工业的三大研究课题之一。 With the development of industry and the increase of population, the demand for timber in various countries in the world has been increasing in recent years, while the volume of logging and growth of timber lags behind the increase in demand. In order to solve the contradiction between supply and demand of timber, many countries, in addition to expanding forest resources and improving the comprehensive utilization of timber, also actively create synthetic timber. In Japan, for example, research into synthetic wood has been included in one of the three major research topics in national industry.
