油松(pinus tabulaeformis Carr)是我国北方的主要造林树种之一。分布范围较广,北至大青山,南达巴山,东至蒙山,西到祁连山东段。垂直分布于海拔500～2,700米之间,随纬度升高而降低。在分布中心的华北,一般海拔1,500～1,900米,且有大面积纯林。目前,我国北方广泛用于营造用材林、水土保持林等。研究油松飞播造林,对于加速林业建设,迅速绿化荒山,控制水土流失,促进农业生产有着重要的意义。
Pinus tabulaeformis Carr is one of the main afforestation species in northern China. Distribution of a wide range of north Daqingshan, South Daba Mountain, east of Meng Mountain, west of the eastern section of Qilian. Vertical distribution at an elevation of 500 ~ 2,700 meters, with the latitude decreases. North China in the distribution center, generally 1,500 ~ 1,900 meters above sea level, and a large area of pure forest. At present, north China is widely used to create timber forests, soil and water conservation forests. Studying the aerial seeding of Pinus tabulaeformis plays an important role in accelerating forestry construction, rapidly greening barren hills, controlling soil and water loss and promoting agricultural production.
