摘 要:随着我国经济建设持续快速发展,木材刚性需求不断增加,木材安全问题受到广泛关注。基于历次全国森林资源清查结果,对我国用材林资源的权属、起源、龄组、树种等基本情况及分布特点和发展趋势进行了阐述,对我国近70年的木材产量、目前的木材需求及木材安全进行了分析。从建设国家储备林基地、大力培育珍贵用材和大径材、加强森林科学经营、提倡木材节约代用、引导规范木材进口等5个方面,提出了保障木材安全的建议。Along with continuous and rapid development of economic construction in China,the rigid demand of timber is increasing continuously,and the issue of timber safety is extensively concerned.Based on the results of previous national forest inventories of China,the basic situation of timber resources,such as ownership,origin,age group and tree species,and distribution characteristics and development trends of timber resources in China were firstly described.Then,the timber production in the past 70 years,current timber demand and timber safety were analyzed.Finally,some suggestions were put forward on ensuring timber safety from following five aspects:building national reserve forest base,cultivating precious-species and large-diameter timber forests,strengthening scientific forest management,advocating timber saving and substitution,and guiding and regulating timber import.
