Carbon in the Vegetation and Soils of Great Britain

摘要

·The total amount of carbon held by vegetation in Great Britain is estimated to be 114 Mtonnes. · Woodlands and forests hold 80% of the G.B. total although they occupy only about 11% of the rural land area. Broadleaf species hold about 50% of the carbon in woodlands and forests. · A map of carbon in the vegetation of Great Britain at 1 km × 1 km resolution based on land cover identified in the I.T.E. Land Cover Map is presented. The predominant location of vegetation carbon is the broadleaved woodlands of southern England. · The amount of carbon in the soils of Great Britain is estimated to be 9838 Mt (6948 Mt in Scotland and 2890 Mt in England and Wales). · In Scotland, most soil carbon is in blanket peats, whereas most soil carbon is in stagnogley soils in England and Wales. · The carbon content of the soils of Great Britain is mapped at 1 km × 1 km resolution. Scottish peat soils have the greatest density of carbon and in total contain 4523 Mt of carbon, 46% of the G.B. total.
