对油松纯林地表可燃物状况进行了初步研究，结果表明：５ ～１７ 年生的人工油松纯林地表可燃物载量与林龄呈直线关系，与郁闭度呈指数关系；灌木载量与林龄、郁闭度均呈指数关系；草载量随林龄的增加而减少。
The results showed that there was a linear relationship between the combustible load on the pure plantation of Pinus tabulaeformis and its stand age and an exponential relationship with canopy density And forest age, canopy density are exponential relationship; grass load decreases with increasing age.
