我国森林资源总量不足,分布不均衡的问题十分突出,林业发展速度明显低于国民经济和社会发展的速度。全国范围内生态环境“局部改善,整体恶化的趋势没有得到根本好转,水土流失日趋严重,荒漠化面积不断扩大,生物多样性受到严重破坏,自然灾害频繁发生。生态问题已成为制约国民经济 The problem of insufficient and uneven distribution of forest resources in our country is very prominent. The development speed of forestry is obviously lower than that of national economy and social development.

The area of ​​desertification has been constantly expanding. Biodiversity has been severely damaged and natural disasters have taken place frequently.
