近代科学与社会实践证明了农业和林业是密切相关的。搞好农业,必须有一个较好的环境条件,保持生态平衡,因此就必须把林业搞上去,使农业与林业保持相应的发展比例,保证林业占有一定的位置。最近国外一些学者认为:一个国家(地区)的富强,常与木材自给率和森林功能的发挥有关。他们把森林覆盖率分作三种情况,在20％以下的为低;20—30％为中;33—50％以上为高。并认为一个国家的森林覆盖率低时,不但木材不能自给,其国土也难以得到保安。还有一些专家估计,农、林、牧三者比例应为2:1:1较为合适。
Modern science and social practice have proved that agriculture and forestry are closely related. To do a good job in agriculture, we must have a better environmental condition and maintain an ecological balance. Therefore, we must push forestry up so that agriculture and forestry will maintain their corresponding proportions of development so as to ensure that forestry occupies a certain position. Recently, some foreign scholars think: the prosperity of a country (region), often with the wood self-sufficiency rate and the functioning of the forest function. They divided forest cover into three categories, with low rates below 20%; medium rates ranging from 20-30%; high rates above 33-50%. And think of a country’s low forest coverage, not only wood can not be self-sufficient, its territory is also difficult to get security. Some experts also estimate that the ratio of the three farming, forestry and animal husbandry should be 2: 1: 1.
