STUDY THE POSSIBILITY OF CO2 FIXED IN SOME NATURAL FOREST CONDITIONS IN BO TRACH DISTRICT, QUANG BINH PROVINCE

Abstract

The calculation of carbon absorption capacity of the current forest conditions are meant to pay the price for environmental services of forests and meaningful in the services payment of absorbing carbon of forests that have been deploying by developing countries. The research results have identified fresh biomass, dry biomass accumulation and carbon content of natural forest conditions in Bo Trach district; 1). Fresh biomass:Rich forest:354.122kg/ha, the average forest 222.122kg/ha, poor forest 142.955kg/ha, forest reserves do not have 6394 kg/ha; 2). Sinh dry mass: Rich forest: 259 379 k / ha, the average forest 160 778 kg/ha, poor forest 102 564 kg/ha, forest reserves without 4171kg/ha; 3). Carbon accumulation: Rich forest: 109 581 kg/ha, the average forest 68 507 kg/ ha, poor forest 43 871 kg/ha, reforestation of forest  1,814 kg/ha.
