我省湾沟林业局于一九五八年建局,当时核定年产量十四万至十六万立米。为了满足国家对木材不断增长的需要,到八四年末,平均年产最增加到二十一万立米,出现了过量采伐的严重局面。现年产量已降到十二万立米,所剩的可采蓄积不足400万立米,大多是高山陡坡、零星小块的“山帽材”,机械化作业极端困难。近几年林产品结构有了变化,原木产 Bayou Forestry Bureau of our province in 1958 built the bureau, was approved 140,000 to 160,000 cubic meters annual output. In order to meet the country’s growing demand for timber, by the end of 1984 the average annual output has been increased to a maximum of 210,000 cubic meters and a serious over-exploitation situation has emerged. At present, the output has dropped to 120,000 cubic meters. The remaining recoverable reserves are less than 4 million cubic meters. Most of them are steep hillsides and sporadic small pieces of “mountain-hat timber,” making mechanized operations extremely difficult. In recent years, forest product structure has changed, logs
