chinois. 我国的木材需求日益增长，国内森林资源总量和质量不足，木材供给压力越来越大。第7次普查期间，国内采伐林木蓄积的综合利用率仅56%，超额采伐比例接近60%。而从成过熟林资源来看，近5年内每年可采伐蓄积约49 928.8万m3，87.7%集中在天然林，约3/4处于南部地区。如果保持原有的综合利用率，国内木材供给远远不能满足国内的木材需求。提高综合利用率，控制超额采伐，是缓解供需矛盾、保护国内森林资源亟需重视的问题。

China’s demand for timber keeps growing, but the quantity and quality of domestic forest resources are not satisfying, timber supply pressure also keeps increasing. In the seventh forest inventory period, the comprehensive utilization rate of forest reserves was only 56%, and the over-harvesting ratio reached nearly 60%. According to the mature and over-mature forest resources data, the reasonable annual harvesting in the coming five years is about 4 992.88 million m3, of which 87.7% is concentrated in the natural forest, and about 3/4 is located in the southern region. If the original comprehensive utilization is maintained, we are not able to meet the increasing demand for timber. So close attention should be paid to promoting the comprehensive utilization rate and controlling over-harvested phenomena.
