| Abstract: | Based on the connotation of forest ecosystem services and characteristics of forest ecosystem,the authors adopted the physical and value assessment methods to evaluate economy valuej of forest ecosystem services in Maolan Karst of Guizhou Province. The results showed that the total annual services value of forest ecosystem in Maolan Karst was up to 394,123.79 million yuan,including 15,317.61 million yuan of water holding,22,599 million yuan of water purification,and about 118,844 million yuan of soil conservation,about 15.86 million yuan of carbon fixation and oxygen production,and about 1947.574 million yuan of air purification.Compared with the direct benefits of forest ecosystem,indirect benefits were more important for the survival of human being.Indirect values were 8.61 times more than direct values. |
