Abstract
The literature data is analyzed in order to elucidate the relationship between the amount of chlorophyll per hectare of forest area (chlorop hyll index - CI) and the weight of carbon accumulated in a stand in on e year. CI values amounting to 9 - 15 kg/ha were recorded in about hal f of the stands, which varied in composition and productivity. The max imum CI attained was 24 kg/ha in the pine, birch, and aspen stands, an d 35 kg/ha in the spruce stands. A linear dependence was observed betw een CI, ranging from 6 to 24 kg/ha, and accumulated carbon, with corre lation coefficients of 0.86 +/- 0.05 for the spruce and 0.81 +/- 0.04 for all the other stands. One kilogramm of chlorophyll produced 215 kg C per year in the spruce and 305 - 335 kg C per year in the other sta nds. The feasibility of CI determination by satellite-based measuremen ts of the spectral brightness of forest canopy is discussed.
