我国是一个森林资源贫乏的国家,现有森林资源无法满足国民经济发展的需要。据国家物资部门推算,到2000年我国木材最低需要量为1亿 m~3。全面开发合理利用现有成过熟林资源,再加上广泛开展中幼林抚育间伐,每年总共可生产7000万 m~3,尚有3000万 m~3的缺口。资源危机、经济危困使我国林业生产目前陷入困境。大力营造周期短、产量高、见效快的速生丰产林,建立丰产林基地,将是缓和我国木材供需矛盾的有效途径。1984年林业部通过对洛南县森林资源调查,确定在
Our country is a country with poor forest resources, and the existing forest resources can not meet the needs of national economic development. According to the calculation of the national materials department, by the year 2000, the minimum timber requirement in our country will be 100 million m 3. The full exploitation and rational utilization of existing over-mature forest resources, coupled with extensive middle-aged and young tending, can produce a total of 70 million m 3 per year and 30 million m 3 shortfall. Resource crisis and economic crisis make forestry production in our country in a dilemma. It is an effective way to ease the contradiction between the supply and demand of timber in our country to create a fast-growing and high-yielding forest with short cycle, high output and quick result. In 1984, the Ministry of Forestry confirmed the investigation of forest resources in Luonan County
