摘　　要：落叶松是我国东北地区重要的商业用材林树种之一,在东北地区得到广泛栽培。通过开展落叶松林天然更新机制,促进森林生态系统自我繁衍、自我恢复,实现森林生态环境的自然恢复目标。针对影响落叶松林天然更新的多种因素进行研究,主要包括种子雨和种子库、林分条件和生境等。通过研究分析,建立和完善落叶松林天然更新机制,同时找出其中的制约因素,为人工促进落叶松更新提供借鉴和参考。Lallch is one of the important commercial forest species in northeast China and is widely cultivated in northeast China.By carrying out the natural renewal mechanism of the larch forest,the forest ecosystem can promote its self-reproduction and self-restoration,and realize the natural restoration goal of the forest ecological environment.Various factors may affect the natural renewal of larch forests,including seed rain and seed bank,stand conditions and habitat.Through research and analysis,the natural renewal mechanism of larch forest is established and improved,and the restrictive factors are found out,so as to provide reference for the artificial promotion of larch renewal.
