It is a distinctive feature for Aomori Prefecture that the forest and agricultural ecosystems which are carrying out CO2 fixation through photosynthesis occupy 90 % of the land area. The scales of secondary and other extremely degree industries and human community which are releasing a large amount of CO2 through consumption of materials and energy are highly limited. In this study, Aomori Prefecture was treated as a regional ecosystem. Plant biomass and net primary production on this regional ecosystem on carbon basis were calculated to be 27.6 × 106 t and 4.2 × 106 t?y-1respectively. The biomass and the net primary production per area and per population on this regional ecosystem were estimated to be one of the most large values for the whole of Japan. The total amount of CO2 released through soil respiration from the natural and agricultural ecosystems and through consumption of materials and energy for the industrial processes and human life was 8.2 × 106 t?y-1. This amount correspnded to two times that of the net primary production. Seventy two percent of the total CO2 emission from this regional ecosystem was due to the sum of consumption of various petroleum products for human life, industrial processes and production of electric power. The imported material, of which 89 % was various petroleum products, from other regional ecosystems to this regional one was estimated to be 13 times that of the exported material to other prefectures. Most of the exported material to other regional ecosystems comprised of marine, agricultural and wood items and their processed products.
