Abstract: The component, life form. regeneration, succession and growth characteristics of natural Pinus densiflora communities (PDC) were analysed. Lacking native species, the element of species was simple in natural PDC in Changbai mountain area. The natural PDC succeeded in prime stage, and its procession direction were deeply affected by disturbance. The pattern was weak aggregative for regeneration populations. Productivity of the hazel-PDC was the highest in severeal main types of PDC, and that of the bush clover-PDC and the grass-PDC were following the former's, that of the daurian rhododendron-PDC was the lowest. Management methods of different types of PDC were also proposed.

Key words: Changbai mountain area, Pinus densiflora, Community characteristics, Productivity
