摘　　要：对长白落叶松成片枯死的原因进行了多学科综合研究．结果表明，长白落叶松的成片枯死与病虫害没有直接关系，由于林地高位沼泽的形成，导致根部缺氧呼吸受阻，是落叶松大片枯死的直接诱因．In this paper, the death causes from withering of Larix olgensis in Changbai Mountain area are investigated interdisciplinarily. The results show that the death of L. olgensis is not directly related to forest disease and insect pests, and the formation of high moor on forestland can lead to the lack of oxygen in root zone and the hindering of root respiration, which is a direct cause of L. olgensis death.

关 键 词：长白落叶松 高位沼泽化 死亡原因
