由于作为纸浆工业的原材料 ,因此竹子在非木质林产品中占有重要的位置。然而 ,过量采伐和人口增长 ,热带林的破坏以及工业原料的新需求 ,尤其是纸浆工业 ,导致竹子资源大量减少 ,目前面临锐减的形势。国家农业委员会发表的数字表明 ,1980和 2 0 0 0年的需求与产出为 4 2 5 .0万t和 875 .0万t,需求与供给之间出现增长的差距。可以看出 ,只有通过人工林增长的方法和有效地利用现有的资源才能达到可持续性。 As a raw material for pulp industry, bamboo occupies an important position in non-wood forest products. However, over-exploitation and population growth, the destruction of tropical forests and new demands for industrial raw materials, especially the pulp industry, led to a sharp reduction in bamboo resources. The figures published by the National Agricultural Commission show that the demand and output in 1980 and 2000 were 425 million and 875,000 tons, respectively, and there was a growing gap between demand and supply. As can be seen, sustainability can be achieved only through the growth of plantations and through the effective use of available resources.
