林业政策对森林及相关行业的影响是非常明显的， 森林法 从宏观上确定了我国林业发展的基本方向。有关林业科学的政策则对技术在林业中的作用具有决定性意义。国家对林业生产进行的总体布局和重点林业生态工程的建设使中国的林业建设步入一个新的发展时期。森林是陆地上最重要的生态系统，森林对地球生境的作用是重要的，同时生境的变化也必然导致森林的变化，二者之间必然发生相互影响。在气候变化情景下，中国森林和农林业用地面积将发生变化， 森林覆盖率将会在１７ ％ ～２０ ．８ ％ 之间。森林面积将增加到１８０ ～２１８

Forestry policy plays a important role to forestry and relative trades. Forestry Law determines the blue map of the forestry development and the part of forestry policy to forestry science determine the effect and place of technique to forest development in China. The layout of forest production and keystone ecological forest project let forestry to a new development phase in China. Forest, which affect earth environment, on the other side, environmental factors change result in forest change, is the most important ecosystem in the land. Forest and environment has an effect each other. Under climate change scenario, there is a change in forest and agora-forest land, and the forest area will increase to 1.8～2.18 million hectares and the forest cover rate will reach 17%～20.8%. For globe change view, forest will turn into carbon sink.
