Study On The Carbon Sequestration Potential Of Major Forest Types In Mountainous Region In Beijing

Nowadays, the rise of greenhouse gases have already caused extreme weather, which has brought inconvenience to the human beings and the social development. This has been intensively noticed by governments and scientists. Because of its carbon sequestration, forest occupies irreplaceable function for the eco-system. Located in the warm temperate zone, Beijing, the capital of PRC, is being paid attention for its carbon sequestration. Long before, many experts tried to do research of the local carbon sequestration in Beijing through many ways, yet because of using existing formulas and references, they didn’t make unified standard which suited this region. Besides that, they didn’t take age of forest into consideration, ignoring the carbon reserves of the jungles and restrains layer.Choosing the artificial Pinus tabulaeformis in Beijing as the object of study, this research founded the allometric biomass of the P.tabulaeformis according to different elements (branches, leaves,trunks) with nested regression approach.And it confirmed the carbon sequestration ability of dead trees, bush and herbaceous layer as well as soil layer through on-spot research.With the facility of the data collected on-spot and germ plasm resource data collected in Beijing, this research outlined the biomass expansion factor which is suitable to main kinds of trees, thus assuming the whole carbon sequestration potential in Beijing. The result unveils that in2005, the total forest biomass in Beijing was9.8795million tons, with the carbon storage of5.19million tons.lt is estimated that by2015,the forest carbon storage will amount to7.58million tons, with the carbon storage of main vegetation forms will reach to11.71million tons in Beijing.
