科学地确定林木蓄积生长率,是林业生产进行经营和规划的基本要求。为掌握“六五”期间我省国营林场林木蓄积的平均生长率,以及各树种组、龄组的生长率,检验我省的营林水平,并预测近期森林资源消长动态,我院结合1983～1985年全省国营林场二类调查,对林场的林木蓄积生长率进行了调查。现将这次调查的有关情况及成果初步分析如下。
Scientifically determining the growth rate of forest tree planting is the basic requirement for the management and planning of forestry production. In order to grasp the average growth rate of forest reserves in the state-owned forest farms during the 6th Five-year Plan period, as well as the growth rate of each tree species group and age group, test the level of forest management in our province and predict the recent dynamic changes of forest resources, In 1985, the survey of state-owned forest farms in the province investigated the tree-growing growth rate of forest farms. The present investigation and the results of the preliminary analysis is as follows.
