20世纪 90年代 ,世界森林资源遭到严重破坏 ,森林资源大幅度减少。造成森林资源减少的主要原因是自然灾害、毁林开荒以及对林产品需求的增加。但包括中国在内的部分国家森林资源却在持续增长。 2 1世纪世界森林资源减少的趋势仍将持续相当长的一段时间 ,但从整体上看 ,前景是乐观的。森林可持续经营的普遍实施。
In the 1990s,the global forest resources were severely damaged and greatly reduced,resulting from natural disasters,deforestation and cultivation,and the increase of the demand for forest products,etc.Fortunately,the forest resources in some countries including China kept increasing in a sustainable way.In the 21st century,though the decrease orientation of the world forest resources will continue for quite a long time,the prospect is generally optimistic.The popular implementation of forest sustainable operation,the increase of man\|made forests,and the slowing\|down of rising demand for forest products are improtant factors for recovering and devloping the world forest resources.
