ABSTRACT- Pinus rigida was one of the major planting tree species for reforestation throughout the country during last thirty years. It is necessary to evaluate distribution and storage of carbon in this tree with increasing of matured stands. Carbon storage and increment of 31-year-old pine stands with different tree densities and site quality were measured for four years (1997-2000). The carbon storage of this stand was 143,674 kg C/ha and the tree accounted for 62%, soil 38% (0-30cm depth) and forest floor 8% of the stand carbon storage. The carbon increment was 3,467 kg C/ha/yr and decreased in the order of stemwood>branch>needle>stembark. Carbon storage and increment were higher in the high site quality than in low site quality stands on similar tree density. Also, the high tree density on similar site quality showed more carbon storage and increment campared with the low tree density. The results suggest that site quality and tree density are a key factor determining carbon storage and increment in this pine stand.

KEY WORDS: carbon increment, carbon storage, carbon sequestration, climate change
