半天然杉阔混交林分形成、发育与结构特征

Formation, Development and Structure of Semi-natural Mixed Forest of Chinese Fir with Broadleaf Trees

针对砍阔栽杉导致的尖锐矛盾，提出人工栽杉与天然更新阔叶林相结合新的栽培方式．分析半天然杉阀混交林的形成、发育过程，揭示天然阔叶林迹地炼山与不炼山栽杉，所形成林分的种类组成、分布特点、年龄与径级结构、层性等林分结构的差异，为科学培育半天然杉阀混交林提供依据．

This paper puts forward a new culture model which combine planting Chinese fir with regenerating broadleaf forest to resolve the serious consequence caused by felling broadleaf tree to plant Chinese fir,then analyses the formation and development of semi-natural mixed forest, reveals the differences between controlled burning stand and no controlled burning stand in species composition, distribution characteristics,age structure, diameter groups and layering feature. The results provide a scientific basis for culturing seminatural mixed forest of Chinese fir with broadleaf trees.
