全局经理面积57万公顷,林业用地43万公顷,其中有林地19万公顷;活立木蓄积6200万m~3,其中有林地蓄积4900万m~3。 目前每年生产商品材16万m~3,消耗森林蓄积24.6万m~3(按65％的出材率计算)。年总生长率按0.9842％计算,年总生长量为61.683万m~3,自然枯损率按0.253％计算,年总枯损量为15.856万m~3,全局年净生长量为45.827万m~3。但林龄结构很不合理,成过熟林占有林地面积的55％,幼林仅占4.1％。
The global manager area is 570,000 hectares and the forestry land is 430,000 hectares, of which there are 190,000 hectares of forest land. The standing tree stock is 62,000,000 hectares, of which 49,000,000 hectares are forested. At present, there are 160,000 m 3 of commercial products annually, and 246,000 m 3 of forest reserves are consumed (calculated at 65% of the raw materials). The annual total growth rate is 0.9842%, the annual total growth is 61.683 million m ~ 3, the natural loss rate is 0.253%, the annual total loss is 15.856 million m ~ 3, the global annual net growth is 458.27 million m ~ 3. However, the age structure is very unreasonable, over-mature forests occupy 55% of the forest area, young forest only 4.1%.
