Forest Carbon Sequestration: The Impact of Forest Managementg three compartments: living plant biomass (stem, branches, foliage, roots), plant detritus (fallen branches and cones, forest litter, tree stumps, tree tops, logs) and soil (organic mineral humus, surface and deep mineral soil). Trees acquire energy for their living structures through photosynthesisaturated-fat 发表于 2025-3-29 07:46:11
Effects of Forest Age Structure, Management and Gradual Climate Change on Carbon Sequestration and Tadual climate change on timber production and carbon sequestration of Finnish boreal forests with Norway spruce as main (dominant) tree species. Our case study examples demonstrated that over the 90 years simulation period the total timber production was from 16 to 30 % lower in southern Finland und结果 发表于 2025-3-29 13:23:18
