Assessment of the Forestry Carbon Sink Capacity in China

The movement of carbon in the land biosphere is very active. The carbon exchange occurs between the land biosphere and the atmosphere frequently, which is called the activist carbon circulation. Therefore, in addition to forestation and protecting the forests, enhancing the forests management may also make a significant contribution to mitigating the green house effect. Based on several studies, the national carbon storage in the forests is about 5.29times10⁹ TC. However, taking the plants and biomass in to account, the total carbon storage would seem to be higher, about 14.43times10⁹ TC. In China the mean annual increment of carbon sink in the form of biomass is estimated to be 1.2times10⁹ TC, 14.4% of the C emission. By the year 2020, the forest cover rate expected to be 23%. Supposed that the woods volume remains the same, the forestry carbon sink in China will be 7.26times10⁹ TC TC. If the woods volume goes up to 100 m ³/ha, which is the mean level in international, the forestry carbon sink in the whole country will be 11.7times10⁹ TC
