古强峪林场为发展造林事业,自1953年开始封山造林,并陆续扩大林地营造面积,三十年来,人工种植的油松幼林,在林场职工的辛勤培育下,已巍然成林。但近些年,发现油松林受到鼠类的危害,大批的油松植株被鼠啃咬致死。随着油松林面积的扩大,鼠害亦日趋严重,已波及全林区。 For the sake of developing afforestation, ancient Qiangyu Forest Farm has been afforesting the mountain since 1953 and gradually expanding the area for afforestation. Over the past 30 years, the planted young pine forest has grown into a succession under the hard work of forestry workers. However, in recent years, it has been found that Pinus tabulaeformis forest is harmed by rodents. A large number of Pinus tabulaeformis plants are bitten by rats. As the area of ​​Pinus tabulaeformis expands, rodent pests also become increasingly serious and have spread to the entire forest area.
