森林资源是人类社会发展的重要自然资源,木材在国民经济中占有重要地位。但是,我国是一个少林缺材的国家,森林复盖率仅为12.7%,世界的平均森林复盖率22%,而工业发达、人口密集的欧洲,平均为29%;按人口平均拥有的森林面积为2亩左右,按人口平均拥有的木材蓄积量只10M~3,世界的平均水平分别为15.6亩和65M~3。随着社会主义建设的发展和人民生活水平的不断提高,对木材的需要越来越大。虽然每年的木材产量已由解放初的五百多万 M~3增加到1977年的四千多万 M~3但这个增长速度太慢了,不仅满足不了需要,而且供求矛盾越来越突出。国家基本建设投资每万元分配的木材量“一、五”期间为7.3M~3,四、五"期间为3M~3.1978年只有1.4M~3了。当然,我们可以适当进口一些木材以补不足,但这
Forest resources are an important natural resource for the development of human society. Timber occupies an important position in the national economy. However, our country is a country lacking timber and with only 12.7% of forest coverage and 22% of the world’s average forest coverage, compared with an average of 29% in developed and densely populated Europe; average forest ownership by population The area is about 2 mu. The average volume of timber owned by the population is only 10M ~ 3. The world average is 15.6 mu and 65M ~ 3 respectively. With the development of socialist construction and the continuous improvement of people’s living standard, the demand for timber is growing. Although the annual timber output has risen from about 5 million M ~ 3 at the beginning of the liberation to more than 40 million M ~ 3 in 1977, this growth rate is too slow to meet demand and the contradiction between supply and demand has become increasingly prominent. The amount of timber distributed per 10,000 yuan for national capital construction was between 7.3M 3 for the first and fifth period and between 3M and 3 for the fourth and fifth periods, only 1.4M to 3 for 1978. Of course, we could import some Wood to make up, but this
