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。Species composition,diameter distribution,horizontal spatial distribution pattern,degree of species isola-tion,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 op-erating 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 sec-ondary forest.
