Large scale and long term study on forest dynamics

对不同森林类型的大规模样地的长期监测研究结果表明：1)自然干扰对森林群落的结构和动态有重要影响；2)组成物种的响应因自然干扰类型的不同而不同；3)地形格局与当地植被格局密切相关；4)组成物种之间的更新生态位的分配是可以区分的。对种子和苗木进行研究的树种确定了安全的苗木补给地点。构建了描述树木种群动态的矩阵模型，并利用该模型分析了森林群落的结构和动态。在因特网上建立了关于森林社区长期大规模研究的主页。

Results obtained from long-term monitoring studies in large-scale plots situated in various forest types revealed that ; 1) natural disturbance had an important role on structure and dynamics of forest communities, 2) responses of constituent species differed with the types of natural disturbances, 3) there was a close relationship between topographic patterns and local vegetation pattern, and 4) partitioning of regeneration niche among constituent species could be clrified. Safe sites of seedling recruitment were identified for tree species whose seed and seedling studies were investigated. Matrix models for describing tree population dynamics were constructed and used to analyze structure and dynamics of forest communities. Home page on the long-term large-scale studies for forest communities was made on the Internet.
