Daftar Isi:
- The lowland production forest of Kalimantan has been managed that almost the same amount of commercial limber volume could be harvested under Indonesian Selective bogging every 35 year. This was an artificial form of an equilibrium state which the extracted volume could he compensated from the increment volume within 35 years. The equilibrium state is essential in liirest utilization to assure the sustainahility of timber production. The objectives of this study were to construct a diameter distribution of long,-term timber production model in the expected equilibrium slate and to compare it with the diameter distribution beforc selective. logging. The research plots data of Silvicul tura! Treatment tier the Regeneration of I.ogged-over Forest in East Kalimutan Project were used to generate elements of long-term timber production model, i.e. recruitment rate and explanation rate which should he described in function. The cubic function was then applied to describe both rates. The two accepted equations were used to quantify the diameter distribution ollong-tenu timber production model. the quantified diameter distribution was compared to that before selective logging in term of stems concentration and volume composition. Finally, the quantified diameter distribution was examined to determine whether the resulted limber volume of both exploitation and recruitment remained the same. The result showed that the cubic function could be used to describe the recruitment rate and the exploitation rate. Based on both equations the diameter distribution of long-term timber production model could he quantified using this ibrmula: (p e ) X --= X " 12,-1 where .V: number of stems. i: diameter class. p
