江边林业局是我省解放以后最早建立的森工局。曾经为社会主义建设和人民生活,作出了重要贡献。但是,长期以来,由于种种原因,以营林为基础,长期经营永续利用的方针,未能得到认真的贯彻执行,因而在不同程度上出现后续资源跟不上、林令结构不合理、林分质量降低等的后果。最近几年来,木材产量只能徘徊在5万立方米左右。据调查森林资源已从1961年的512万立方米,递减为1978年的341万立方米。其幼中成林比例由2∶3∶5变成5∶3∶2,其中利用资源仅80多万立方米,按70%的出材率计算仅有50多万立方米出材量。如按历史上的平均年产量9万立米计算,则不要几年利用资源即消耗殆尽,木材生产将要间断。
Waterfront Forestry Bureau is the earliest established after the liberation of our province Senate Bureau. Once made an important contribution to the construction of socialism and people’s life. However, for a long time, due to various reasons, based on silviculture, the principle of long-term management of sustainable use has not been earnestly implemented. Therefore, follow-up resources are not kept up to varying degrees and the structure of the tree is not reasonable. Sub-quality reduction and other consequences. In recent years, timber production can only hover around 50,000 cubic meters. According to the survey, forest resources have been reduced from 5.12 million cubic meters in 1961 to 3.41 million cubic meters in 1978. The proportion of young children into forests from 2: 3: 5 into 5: 3: 2, of which only about 800000 cubic meters of resources, according to the 70% of the output rate of only 500000 cubic meters of wood output. If the historical average annual output of 90,000 cubic meters, then do not take a few years to use resources that are depleted, timber production will be interrupted.
