摘要: 2006—2007年在长白山相同海拔的阔叶红松林和白桦林样地内研究了啮齿动物和鸟类对红松球果种子的消耗情况.结果表明:阔叶红松林中啮齿动物对红松球果种子的消耗量明显大于鸟类(P<0.01),而白桦林中鸟类的消耗量明显大于啮齿动物(P<0.01);两林型中啮齿动物的总消耗量明显大于鸟类,二者差异极显著(P<0.01).啮齿动物对阔叶红松林中埋藏种子的消耗量显著多于白桦林,两林型中啮齿动物对埋藏种子的消耗量均随埋藏深度的增加而减少.

Abstract: An investigation from 2006 to 2007 was made on the Pinus koraiensis seed consumption by rodents and birds in the broadleaved P. koraiensis mixed forest and birch forest at the same altitude in Changbai Mountains. The results showed that in broadleaved P. koraiensis mixed forest, rodents consumed more pinecone seeds than birds; while in birch forest, birds did more than rodents. In the two forests, the total number of pinecone seeds consumed by rodents was significantly higher than that consumed by birds (P<0.01). In addition, rodents consumed more embedded seeds in broad-leaved P. koraiensis mixed forest than in birch forest, and the consumption amount in the two forests decreased with increasing embedded depth.
