英文摘要	Forest ecosystem provides mankind with many important products and services. However, man is not fully aware of the significance its services. Consequently, man has exploited the forest resources predatorily and managed them extensively, which in turn leads to the decrease of the size of forest and the weakening of the various services provided by the forest ecosystem. According to the characteristics and structure of the forest ecosystem of Chongqing, this paper divides the forest ecosystem services into four categories-provisioning services, regulating services, supporting services and cultural services. Taking the year of 2006 as the base year, this paper assesses seven ecosystem services provide by Chongqing forest ecosystem and evaluates qualitatively their economic values with recourse to market value method and production cost method. The research findings are as follows: the provisioning services of forest products have increased 45.82%, from 3.514 billion yuan in 2006 to 5.124 billion yuan in 2011. Forest carbon storage totals 62902000 tons, nearly an increase of 1million tons from the year of 2006. The water conservation value of the forest ecosystem in Chongqing is 97.711 billion yuan in 2006, whereas it reaches 103.632 billion yuan in 2011, an increase of 5.921 billion yuan. The erosion control capacity and quantity have also increased. The climiate regulation value has increased to 91.344 billion yuan in 2011 from 95.930 billion yuan in 2006, a net increase of 4.586 billion yuan. The total value of landscape tourism was 45.06 billion yuan in 2006, whereas it has increased to 70.2billion yuan in 2011. the net increase was 6.834billion yuan. Therefore, it is safe to say that the Project of Forest Chongqing has brought limited direct economic value, but it has contributed tremendous to the development of tourism in Chongqing. In terms of types of services, the value order goes as follows: Water Conservation>climate regulation>Landscape Tourism >Biodiversity Conservation> Soil Conservation>Carbon Sequestration. Since the forest ecosystem of Chongqing is highly valuable, more effort should be made to make people aware of the significance of the forest ecosystem. The research findings of the paper can provide scientific basis for the management, protection and compensation of ecosystem.
