摘要
对低质油松中龄林进行拯救伐而后封山育林5a的试验结果表明:对确无培育前途,但具有天然更新能力的油松中龄林,进行拯救伐而后严加封禁,能达到以封代造、恢复森林植被的目的,并且,比人工造林投资小。
The 5-year experiment with a deteriorated Chinese pine stand shows that, for the mid-aged pine stand with little value in further management but having the ability to regenerate, salvage cutting and land closing are the effective ways for recovering the forest vegetation instead of planting. Moreover, this method costs less than planting.
