Establishing a carbon stock baseline for the degraded vegetation in Cam Pha city, Quang Ninh province
In Cam Pha city (Quang Ninh province) there existes a lot of vegetation having a high degree of degradation. Findings of the research plots located in 4 years (2012-2015) have shown that, vegetation IC has the largest biomass (biomass fresh: 78.70 tons / ha; dry biomass: 36.65 tons / ha), fol- lowed by the grass vegetation (fresh biomass: 62.08 tons / ha; dry biomass: 25.67 tons / ha ). Vegetation IA has the lowest biomass (biomass fresh: 33.73 tons / ha; dry biomass: 15.18 tons / ha). The average amount of accumulated carbon in the biomass of vegetation IC is 18.33 tones / ha, in that vegetation IA was 7.60 tones/ ha, in the grass vegetation is 12.84 tones / ha. During the ecological succession, vegetation IC showed an increase in the ability to accumulate carbon (the amount of biomass carbon accumulation of vegetation IC in the 4th year was 21.97 tons / ha). In addition, the paper also proposed the suitable methods of using degraded vegetation in Cam Pha city, Quang Ninh province.
