南朝鲜的林业南朝鲜的森林面积约650万公顷,相当于国土的66%。据推测,林木蓄积量为15亿m~3,其中大部分在二龄级以下,每公顷的材积只有22m~3。即使在这样的情况下,木材加工品的出口量也很大,一年原木消耗750万m~3,其中83%却依靠进口材。

South Korea’s Forests South Korea has about 6.5 million hectares of forest, equivalent to 66% of the country’s territory. It is speculated that the stock volume of forest is 1.5 billion m 3, most of them below the second grade, and the volume per hectare is only 22 m 3. Even in this case, the export of processed wood products is also very large, a year consumption of 7.5 million m 3 logs, of which 83% rely on imported materials.
