흉고직경과 수고에 의한 소나무(Pinus densiflora S. et Z.)의 지상부와 지하부 생체량 추정 = Estimating Above- and Below-ground Biomass from Diameter of Breast Height and Height for the Pinus densiflora Sieb. et Zucc

다국어 초록 (Multilingual Abstract)

This study was conducted to elucidate the relationship between the root structure and the crown structure of Pinus densiflora S. et Z., and thereafter to obtain the regression equation for the estimation of relative root and needle biomass using the tree height and diameter of breast height(DBH) without measurement of root and needle biomass. The study sites was Gyeongsan, Ulzin and Kyeongju stands located in south eastern part of Korea. Five dominant or co-dominant trees of 25 to 45 year-old were selected in each site and tree height, diameter of breast height, tree age, weight of total needle and branch, cross section and sapwood area at breast height were measured for biomass of above ground part. And also for biomass of below ground part, the length of root, the number of root, the weight of root, the cross section area of root etc. by dividing the horizontal and vertical roots were measured. The significantly correlation was shown between the biomass of most of variables of above ground parts and those of below ground parts, and the biomass of above- and ground parts was not significantly correlated with the age of tree. The regression equation for the diameter of breast height to the total weight of root was Y=-9.39+2.80X and decision coefficient was 0.67 and also to the total weight of needle, regression equation was Y=-16.52+ 1.79X and decision coefficient was 0.86. The regression equation of the tree height to the weight of horizontal root was Y=-5.54+1.00X(r²=0.71) and to the total weight of needle, regression equation was Y=-23.00+3.41X(r²=0.83). The weight of total branches and needles, and the sapwood area at breast height of above ground parts showed highly positive relationship with below ground biomass. The results obtained from this study can be used to the estimating of biomass of below ground using variables of above ground such as DBH and tree height of the 25 to 45 year-old Pinus densiflora stands.
