Forest Ecosystem Services Valuation of Upper Reaches of Dahuofang Reservoir

In this paper, we assess the value of forest ecosystem services of the study area by using market value method, opportunity cost method, shadow price method, cost analysis method, shadow project method, travel cost method and alternative cost method. The results showed that the total annual service value of forest ecosystem in the study area is up to 101.07 ×10^8 yuan/a, of which 2. 19 × 10^8 yuan/a for material production, 33.93 × 10^8 yuan/a for atmosphere regulation, 12 × 10^8 yuan/a for water regulation, 23. 66 ×10^8 yuan/a for environmental purification, 8. 62 × 10^8 yuan/a for soil protection, 12. 17 ×10^8 yuan/a for maintenance of biological diversity, 8.49 ×10^8 yuan/a for leisure. The results show that the study area＇s forest ecosystem has perfect function in atmosphere regulation, water conservation, flood storage, soil conservation et al. So it＇s valuable to protect.
