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.
