Abstract: Facing the relative lag of forest ecosystem service and estimation in China, this paper proposed to quickly carry out the research on the evaluation of forest ecosystem service.On the basis of the classification of forest ecosystem types in China,the service of artificial and semi-artificial forest ecosystems was investigated,which was divided into eight types,i.e.,timber and other products,recreation and eco?tourism,water storage,C fixation and O2 release,nutrient cycling,air quality purifying,erosion control,and habitat provision.According to the assessment index system for global ecosystem service proposed by Costanza et al.,a series of assessment index system suitable for Chinese forest ecosystem service was set up,by which,the total value of forest ecosystem service in China was estimated to be 30 601.20×108 yuan·yr-1,including direct and indirect economic value about 1 920.23×108 and 28 680.97×108 yuan·yr^-1,respectively.The indirect value was as 14.94 times as the direct one.The research aimed to bring natural resources and environment factors into the account system of national economy quickly,and to realize the green GDP at last,which would be helpful to realize sustainable development and environment protection.
