一、我国木材生产概况我国土地面积95.925万公顷,有林地面积12.186万公顷,占国土面积12.7%(即森林覆盖率)。森林资源蓄积95亿立米大部分是天然林,主要分布在东北,西南边远山区和江河的水源地。除新疆、西藏的木材目前无法运出来外,近三年来我国木材生产量(见表一)基本上稳定。在年生产量5000万立方米左右,近三~五年内,受限于我国森林资源影响,我国的木材生产量将不会有明显的变化。
First, the overview of China’s timber production China’s land area of 959.25 hectares, with forest land area of 1218600 hectares, accounting for 12.7% of land area (ie, forest coverage). Most of the 9.5 billion cubic meters of forest resources are natural forests, mainly distributed in the water sources of the northeast, remote mountainous areas in the southwest and the rivers. In addition to Xinjiang, Tibet’s timber can not be shipped out at present, China’s timber production in the past three years (see Table I) is basically stable. In the annual production of 50 million cubic meters, nearly three to five years, subject to the impact of China’s forest resources, China’s timber production will not be significantly changed.
