一、林分改造的重要性林分改造是苏联林学家在林业上一个重要创造,已被广泛地应用于恢复经济价值高的林分中去。目前,我省的残败林以及经济价值低劣的林分还很多,为了将经济价值低,生产力不高的林分改变过来。我们曾与58年春在桥山林区的建压选定试点,进行了此项工作的小型试验,给恢复我省残败林和生产力不高的林分。作一初步的研究。 I. The Importance of Forest Rehabilitation Forestry restoration is an important creation of forestry by Soviet forest scientists and has been widely applied to restore the forest with high economic value. At present, there are still many remaining forests in our province, as well as poorly-affluent forests, in order to change the low-productivity and low-productivity forests. We conducted a pilot experiment with this project in the spring of 58 years in the Qiaoshan Forest Zone to give a small experiment to restore the remaining forests and productivity in our province. Make a preliminary study.
