| Abstract: | This paper evaluated the forest ecosystem services of Dazhongshan Nature Reserve and provided data supports to the decision-makers based on the field investigations and researches. Beginning with the concept of forest ecosystem services, the authors adopted the eeo-economy evaluation methods and classified the forest ecosystem service of Dazhongshan Nature Reserve into direct and indirect benefits. Direct benefits of forest ecosystem mainly include the income form timber and tree crops products; indirect ecosystem service of forest is the principal part of its environment protection function and consists of water resource and soil conservation, air and water resource purification, carbon fixation and oxygen production. The total value of forest ecosystem services of Dazhongshan Nature Reserve is up to 514.8 million yuan/a（Chinese RMB）per year,of which, direct benefits makes up 2.91% and are about 15 million yuan/a,whereas indirect benefits make up 97.09% and are 499.8 million yuan/a,which consist of 30.9 million yuan/a of water-holding,5.3 million yuan/a of water purification,and about 151.6 million yuan/a of soil conservation, about 177.4 million yuan of carbon fixation and oxygen production, about 133.7 million yuan/a of air purification. Compared to the direct benefits of forest ecosystem,indirect benefits are more important for the survival of human being. |
