Abstract
This study was conducted to examine the biomass and energy content of 60- to 70-year-old Quercus mongolica stand facing northern and southern aspect in Mt. Baekwoon (800 m above sea level), Gwangyang, Jeollanam-do and in Mt. Halla (1,000 m above sea level), Jeju-do. The total biomass was 288.4 ton/ha in northern aspect and 241.9 ton/ha in southern aspect of Mt. Baekwoon while 368.4 ton/ha in northern aspect and 364.3 ton/ha in southern aspect of Mt. Halla. Annual net production was 20.7 ton/ha/yr in northern aspect and 17.7 ton/ha/yr in southern aspect of Mt. Baekwoon while 19.0 ton/ha/yr in northern aspect and 21.2 ton/ha/yr in southern aspect of Mt. Halla. Total biomass and annual net production of Mt. Halla were greater than those of Mt. Baekwoon. The net assimilation rate (NAR) was 5.05 in northern aspect and 4.09 in southern aspect of Mt. Baekwoon, while 4.60 in northern aspect and 3.66 in southern aspect of Mt. Halla, Total energy content was 5,666 GJ/ha in northern aspect and 4,793 GJ/ha in southern aspect of Mt. Baekwoon while 6,550 GJ/ha in northern aspect and 6,435 GJ/ha in southern aspect of Mt. Halla. Annual energy content was 365 GJ/ha/yr in northern aspect and 360 GJ/ha/yr in southern aspect of Mt. Baekwoon while 351 GJ/ha/yr in northern aspect and 347 GJ/ha/yr in southern aspect of Mt. Halla. Annual energy content of Mt. Baekwoon was greater than that of Mt. Halla.
