본 연구의 목적은 경남 산청 지역에 분포하는 40년생 리기다소나무 임분을 대상으로 지상부 바이오매 스와 순생산량에 대하여 분석하고자 하였다. 본 연구의 결과에 의하면, 지상부 바이오매스량은 127.7 Mg ha-1으로 나타났고, 줄기 103.1 Mg ha-1, 가지 17.2 Mg ha-1, 잎 7.4 Mg ha-1으로 나타났으며, 바 이오매스 함량은 줄기목질부 (71.1%) > 가지 (13.5%) > 줄기 수피 (9.6%) > 잎 (5.8%) 순으로 나타났다. 또한 지상부 순생산량은 10.4 Mg ha-1로 나타났고 줄기 3.6 Mg ha-1, 가지 2.2 Mg ha-1, 1년생 소지 1.3 Mg ha-1, 잎 2.8 Mg ha-1로 나타났다. 순생산량 함량은 줄기 목질부 (34.6%) > 잎 (26.9%) > 가지 (21.2%) > 소지 (12.5%) > 줄기 수피 (4.8%) 순으로 나타났다.

This study was conducted to estimate the aboveground biomass and net primary production of 40 year old Pinus rigida forest in Sancheong, Gyeongnam province. The aboveground biomass was 127.7 Mg ha-1 and 103.1 Mg ha-1 of which were found from stem, 17.2 Mg ha-1 from branch and 7.4 Mg ha-1 from leaf. Biomass distribution ratio of Pinus rigida stands showed the highest in stem wood with 71.1%, followed by the branch with 13.5%, stem bark with 9.6% and lastly the leaf with 5.8%. Net primary production of aboveground biomass was 10.4 Mg ha-1 and 3.6 Mg ha-1 were found from stem, 2.2 Mg ha-1 from branch, 1.3 Mg ha-1 from twig and 2.8 Mg ha-1 from leaf. Net primary production distribution ratio of Pinus rigida was 34.6% on stem wood, 26.9 on leaf, 21.2% on branch, 12.5% on twig and 4.8% on stem bark.
