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 万公顷
The impact of forestry policy on forests and related industries is very clear. Forest Law sets the basic direction for the development of forestry in our country. Policies relating to forestry science are decisive for the role of technology in forestry. The overall layout of the state for forestry production and the construction of forestry eco-engineering put China’s forestry construction in a new period of development. Forests are the most important ecosystems on land. The role of forests on the Earth’s habitat is important. At the same time, changes in habitats will inevitably lead to changes in the forests, which inevitably affect each other. Under the climate change scenario, the area of forest and forestry land in China will change, and the forest coverage rate will be 17% -20. 8% between. The forest area will increase to 180 ~ 2180000 hectares
