提高森林单位面积的木材商品生产率和合理的利用国家森林资源,被规定在1976—1980年苏联国民经济发展的总方针之中。乌克兰的森林生长率较高,平均每年每公顷生长量为3.72m~3,超过全苏联平均的1.8倍。在共和国的国有森林资源中,高疏密度(p=0.7-1.0)的林分约占森林覆盖面积的75％左右。疏密度0.4—0.6的林分占24％,而0.3以下的仅为1％。但是在森林总 The improvement of forest commodity productivity per unit of area and the rational use of national forest resources have been stipulated in the general guidelines of the Soviet national economy in 1976-1980. Ukraine has a high forest growth rate, with an average annual growth rate of 3.72 m 3 per hectare, more than 1.8 times the average for the entire Soviet Union. Among the state-owned forest resources in the Republic, high-density (p = 0.7-1.0) stands account for about 75% of forest cover. Silos with a density of 0.4-0.6 accounted for 24%, while only 1% below 0.3. But always in the forest
