| Abstract: | In this paper,we assess the value of ecosystem services function in upper reaches region of Dahuofang reservoir 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 ecosystem in the study area is up to 127×108yuan/a,of which 22.502×108yuan/a for material production,38.93×108yuan/a for atmosphere regulation,19.923×108yuan/a for water regulation,24.373×108yuan/a for environmental purification,8.624×108yuan/a for soil protection,12.647×108yuan/a for maintenance of biological diversity.The results show that the study area＇s eco-system has perfect function in atmosphere regulation,water conservation,flood storage,soil conservation et al.So it＇s valuable to protect. |
