Analysis Distribution of Biomass Carbon of Grasslands, Shrubs, and Rainfed Rice Fields on Dry Land in the Aceh Besar District Indonesia

Abstract This research was conducted to determine plant biomass, carbon potential, and CO 2 reserve potential in understory vegetation general, namely grasslands, shrubs, rainfed rice fields. The sampling of the carried out randomly intentionally, limited reeds, shrubs land bushes Aceh Besar District Indonesia. sample taken based on a digitized map obtained from overlaying use map, slope soil type government map. Measurement biomass Imperata, fields is accordance with procedures Indonesian National Standard (2011) World Agroforestry Center. area bush larger than that grasslands. In plants found are Acacia leucoeplhoea , Mimosa pudica Cyperus rotundus, Eleusine indica . Grassland has one only, namely, Pennisetum purpureum consists Oryza sativa plant. Plant [C] content, greater grassland fields, as well reserves, total reserves. Shrubs woody render for carbon, absorption increase followed by an storage. Parameters affect indirectly will also storage ecosystem, individual density, stem diameter, tree species diversity, soil. density trees stocks through biomass. because does not only consist undergrowth, but stems such leucoeploea, making stock cover 96,962.2 ha, hence grasslands
