Effects of the land use change on ecosystem service value

The impacts of land utilization change on the ecosystem service values in Daqing during1995 to 2015 were analyzed based on unit area ecosystem service value of Chinese territorial ecosystemfrom Mr. Xie Gaodi and ecosystem service value calculation formula from Costanza. Results showed thatthe ecosystem service value of Daqing decreased from US $4343.1559m in 1995 to US $3824.327m in2015, with the ecological value of US $518.8289 m decreased during the past 20 years. Wetland and waterbody were the two main land utilization types with the greatest contributions to the ecosystem service value.Ecosystem services value of per capita decreased 23.52%. The sensitivity coefficient of eco-service valuesof all types of land utilization to their value coefficients were all less than 1 in Daqing area. The sensitivitycoefficients followed that wetland > water body > woodland > unutilized land > pasture land> cultivatedland in 2015, which indicating that the changes of the land utilization are lack of flexibility to the changesof the ecosystem service value.
