Abstract

The aims of the research are to identify biomass and estimate carbon stock of woody floor at some forest status in Bach Ma National Park and to recommend some solutions in order to improve the effectiveness of forest management toward sustainable development. Collecting the relative data through articles, books, internet information and organizations and inheriting the data from previous research on biomass and carbon stock. Moreover, the research implemented field surveys by designing 31 circular plots (1,256 m2) with three radii including 4 m, 14 m and 20 m for measuring trees from 5 to 20 cm, 20-50 cm and > 50 cm DBH (diameter at breast height), respectively. Correspondingly, D1.3, H were measured. The results showed that biomass of rich, medium and restoration for- ests are 144.16, 43.17 and 20.31 ton/ ha, respectively. The total average C-stock is calculated as follows: rich forest 264.53 (ton/ha), medium forest (79.21 ton/ha) and restoration forest (37.27 ton/ha). Therefore, the rich forest has the highest CO2 absorption (399.78 ton/ha). Meanwhile, CO2 absorption of medium and restoration forests are 133.13 ton/ha and 46.81 ton/ha.
