黑龙江中部阔叶混交林空间结构特征分析
Spacial Structure Analyses of Mixed Broad leaved Forest in Central Heilongjiang Province
【摘要】 文章对黑龙江中部地区疏伐和未疏伐的阔叶混交林进行了树种组成、直径分布、水平空间分布格局、树种隔离程度、林木大小分化程度、林木竞争指标和竞争压力进行了合理分析,阐明经营性疏伐是调整阔叶混交林树种组成、直径分布和空间结构的重要技术措施,为更加合理经营天然次生林提供科学依据。
【Abstract】 Species composition,diameter distribution,horizontal spatial distribution pattern,degree of species isolation,differentiation of the size of forest and competitive index & pressures of forest of mixed broad-leaved forest with & without thinning in central region of Heilongjiang Province were reasonably analyzed.It is clarified that operating thinning is important technical measure to adjust species composition,diameter distribution and spatial structure mixed broadleaved forest,which provides a scientific basis for more rational management of natural secondary forest.
