Abstract
This is a report concerning a method to present horizontal distribution maps of biomass (carbon stock) and CO2 fixation of vegetation in some wide area, TOYOTA Foresta Hills. Reading the mesh-screened vegetation map and aerial photographs, the ratios of vegetational component in every mesh were deceided. As for the forest vegetations stem volume and its increment recorded in the Forest Register (data base for forest management planning) were avairable to estimate both total biomass and CO2 fixation by the calculations with some constant values by forest type. On the others than forest the suitable figures of biomass for each vegetation were employed, but their amounts of CO2 fixation were not counted because their carbon incomes as net production change to outgo as decomposition in a short period. Figures in each mesh were holizontaly mapped and summed up as the total amounts in the area.
