Ecosystem Service Value Based on Land Use Change in Daqing

Based on land use data in 2001 and 2009,and the Costanza's method and the coefficients proposed by Gao-di Xie,this paper quantitatively examined the variation of ecosystem services value on land use change in Qaqing.The results showed that the areas of the forest land,urban and rural settlements and industrial land increased from2001 to 2009,and all of others decreased during the period.Change of the forest land were more remarkable.Land use change led to the change of ecological environment in the research area and influenced the ecosystem service value to some degree.The gross ecosystem service value in Daqing increased 41170.55 million yuan during the 9 years.Besides,the value changes of 9 types of ecosystem services were analyzed.The ecosystem service functions of water resource conservation,waste disposal and food supply by the ecosystem decreased,whereas the rest all increased.The analysis of ecosystem services value on different types of land use showed,ecosystem service functions of wetlands and waters were stronger than others,only the ecosystem service value of forest land increased.
