Large scale and long term study on forest dynamics

在各种森林类型的大规模试验区进行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）组成树种对不同类型干扰的响应不同，3）地形格局与当地植被格局有密切关系，（4）更新生态位在各组成种间的分配是明确的。确定了安全的网站的幼苗招聘树种的种子和幼苗的研究进行了调查。建立了描述树木种群动态的矩阵模型，并用于分析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.
