摘　　要：本文根据1959年在凉水自然保护区(128°53′E;47°10′N)发现的一片次生黄波罗林的三次复查资料,对林分的种类组成、层次结构、生长和营养特性等进行了系统的分析。证明黄波罗纯林不稳定,伴随着其它阔叶树的侵入,黄波罗成分逐渐下降,由纯林逐步演化为混交林。在群落树种更替过程中黄波罗和山杨等先锋种生长减慢,频度减小,而水曲柳和色木等中庸性硬阀叶树种迅速发展,必将成为未来林分的优势种。在混交林中,山槐能为其提供充足的N素营养,提高森林生产力。According to the cork-tree (Phellodendron amurense) forest survey materials during 1959, 1981, and 1990 in Liangshui Natural Reservat- ion area (47°10′N,128°53′E),this paper studied and systematic analyzed the species composition, vertical structure, growth and nutrition character of a pure secondary cork-tree forest. It has been demonstrated that tke pure cork-tree forest is unstable. With tke continuous invasion of the other broadleaved trees in large quantities, the corktreedecreases their composition in the stand and the forest has been changed into a mixed broadleaved trees forest gradually. In the processes of replacement and succession of the community, the cork-tree and david poplars (Populus davidiana) grow slowly, regenerate poorly and have the tendency to be replaced or overtopped by those tolerant species, such as ash (Fraxinus mandshurica) and maple (Acer mono). These species establish fast and increase in density quickly, so they will become the dominant trees in the future stand composition. In the mixed forest, Maakia amurensis can provide adequate Nitrogen nutrient for the needy species such as the cork-tree, so that the mixed growth between them has greatly improved on the forest productivity.
