Abstract: In order to represent the forest carbon sequestration role of Dongguan Dalingshan urban forest park in low-carbon city development, the variable BEF (Biomass Expansion Factor) method was used to estimate and analyze the carbon storage, density and sequestration of forests based on the forest resource inventory data of 2005 and 2008.The results showed that amount of carbon absorbed by the forest park was 90.69 thousand tons in the three years with an annual absorption at 30.23 thousand tons and annual forest carbon absorption at 7.34 t per year. It shows that the carbon sequestration capacity of urban forest park is remarkable for low-carbon city development.

Key words: Dalingshan, urban forest park, carbon sequestration, low-carbon city
