Stand Structure and Growth Characteristics at Different Elevations of the Korean Pine(Pinus koraiensis) Natural Forest on Mt. Seorak
초록
영어
This study was conducted to analyze the stand structure and growth characteristics along different elevations of Pinus koraiensis natural forests located at mean elevation 1,300 m (site1), 900 m (site2) and 600 m (site3) on Mt. Seorak. Mean DBH and height of P. koraiensis were 25.4 cm and 12.3 m in site1, while that of site2 and 3 were over 40 cm and 20 m, respectively.
For this reason, there was 5 times difference of single tree volume between site1 and other sites(p<0.05). Mean ringwidth increment of P. koraiensis was 1.1 mm/yr in site1, 1.5 mm/yr in site2 and 2.6 mm/yr in site3. However, recent growth of ringwidth has increased by 8.6% in site1, whereas site2 and 3 have fallen by approximately 50% over the last 10 years. These results signify that the growth and distribution of natural P. koraiensis are effected by different climatic environment along elevations.
