一、必须加强人工更新造林的质量管理(一)加强人工更新造林质量管理是国情的需要。我国是个少林国家,森林资源严重不足,人均占有林地面积不足2亩,居世界第121位。这一资源状况加深了林业的主要矛盾,即社会对森林资源的总需求同森林资源可提供的总供给之间的矛盾。为了恢复和扩大森林资源,国家注意了造林工作,建国以来全国造林面积达13亿亩,但保存率只有30%,这一现实,使森林资源的恢复和扩大只是纸上谈兵。
First, we must strengthen the quality of man-made reforestation management (A) to strengthen artificial reforestation quality management is the national needs. Our country is a Shaolin country, and there is a serious shortage of forest resources. The per capita forest land area is less than 2 mu, ranking the 121st in the world. This resource condition deepens the main contradiction in forestry, that is, the contradiction between the total demand of society for forest resources and the total supply that forest resources can provide. In order to restore and expand forest resources, the state has paid attention to the afforestation work. Since the founding of the People’s Republic of China, the afforestation area in China reached 1.3 billion mu but the preservation rate was only 30%. This fact makes the restoration and expansion of forest resources only a piecemeal talk.
