Abstract:

Based on data of the seventh national investigation of forest resource and multiple-years consecutive observation by the long-term Ecological Research Station affiliated to the Chinese Forest Ecosystem Research Network (CFERN), the forest ecosystem services in China was evaluated by using the method of 《Specification for assessment of forest ecosystem service in China》(LY/T 1721—2008),which was published by State Forestry Administration in 2008. The results showed that the total value of the forest ecosystem services in China was 100 147.61×108yuan ·a^-1 in 2009, and the value of the service functions of forest ecosystem was in an order of water conservation＞biodiversity protection＞C fixation and O2 generation＞soil conservation and fertility maintenance＞air purification＞nutriment accumulation. This research also assessed the value of forest ecosystem services in different provinces in China. The forests in southwest, northeast and south of China had relatively higher total valuation of forest ecosystem services. The forest ecosystem services in north China generally had higher total valuation than in the south. The value per unit area in the southern coastal areas was more than in the northwest and central region. This research could provide the scientific basis for the policy of sustainable development and the protection of forest resources.
