冻土之上的兴安落叶松林研究进展

Research Progress of Larix gmelinii Forests on Permafrost

兴安落叶松（Larix gmelinii）林是我国寒温带典型的森林类型,广泛分布于大兴安岭地区,由于其在冻土地区能维持稳定生长而备受关注。本文以寒温带典型针叶林——兴安落叶松林的生理、生态及生长状况为切入点,整理归纳兴安落叶松林的自身特性及其演替更新规律,参照现阶段对于兴安落叶松林的培育经营方式,结合林分实际状态提出合理科学的经营管理手段,以保证大兴安岭兴安落叶松林的稳定健康生长,进而有效提高森林生产力,保持生物多样性,对维持寒温带针叶林区稳定、健康、可持续发展提供理论支持。

As the typical forest type on the cool temperature in China, Larix gmelinii is widely distributed in Daxinganling area, which has attracted much attention due to maintain stable growth on permafrost. In this paper, its characteristics and regeneration were summarized by the physiological and ecological research of Larix gmelinii, and science rational suggestion were put forward based on its cultivating and managing means recently to ensure Larix gmelinii forests could growth stable and healthy and to improve effectively forest productivity and protect biodiversity, which were provided a useful study for managing and making use of the forest and achieving sustainable forest management.
