长白山红松针阔混交林种内、种间竞争关系研究
STUDY ON INTRASPECIFIC AND INTERSPECIFIC COMPETITION OF PINUS KORAIENSIS BROADLEAF MIXED FOREST IN CHANGBAI MOUNTAIN
摘要
Abstract
Using Hegyirs competition index model for individual tree, intra-specific and inter-specific competitions of Pinus koraiensis broadleaf mixed forest in Changbai Mountains were analyzed. Data showed that intra-specific competition intensity for Pinus koraiensis was 0. 269 9, this was reduced with increased diameter classes. Intra-specific competition was much larger than inter-specific competition in Pinus koraiensis broadleaf mixed forest.关键词
