Abstract

Some results of the 5th Korean National Forest Inventory Program measured in 2007 were used to analyze annual diameter growth characteristics for major tree species distributed in Chungnam province. A total of 717 sample trees from 49 plots distributed in Chungnam province were measured and analyzed for annual diameter growth characteristics. As stand age and stand density increased, annual diameter growth rates for major species tended to decrease. The species of Prunus sargentii(2.14mm/yr) showed the best annual diameter growth rates and the others are Quercus serrata(2.10mm/yr), Pinus thunbergii(2.03mm/yr), Pinus densiflora(1.91mm/yr), and Castanea crenata(1.90mm/yr) in order. This information could be very useful to understand annual diameter growth characteristics for major species distributed in Chungnam province.

본 연구는 2007년도 국가산림자원조사 자료 중 충청남도 지역에서 조사된 주요 수종별 연년 직경생장량의 특성에 대하여 분석하고자 하였다. 2007년도 충남지역에서 조사된 고정표본점은 총 49개소이며, 직경생장량 조사를 위해 목편을 채취한 개체목으로 총 717본의 표준목이 측정되었다. 주요 수종들의 연년 직경생장량은 임령과 임분밀도가 증가함에 따라 감소하는 일반적인 경향을 보였다. 연년 직경생장량을 분석한 결과에 의하면, 산벚나무가 약 2.14mm/yr로 연년 직경생장량이 가장 높았고, 그 다음은 졸참나무(2.10mm/yr), 해송(2.03mm/yr), 소나무(1.91mm/yr), 그리고 밤나무(1.90mm/yr) 순으로 나타났다. 이와 같은 정보는 충남지역에 분포하는 주요 수종의 연년 직경생장량 특성을 이해하는데 중요한 정보를 제공해 준다.
