Abstract:: Ganzhou District was taken as the study case. The ecosystem service value changes from 1987 to 2009 under the land use/cover change in Ganzhou District were analyzed. The results showed that: (1)farming and urban land use had an increasing tendency, the ecosystem service value of forestland and grassland fluctuated, first decreased and then increased, water area decreased; (2) the ecosystem service value showed the change of ’V’ shape, first came down and then rose, which were 25.2, 19.53 and 20.21 billion Yuan in 1987, 2000 and 2009, respectively. In different ecosystems, the ecosystem service values of grassland, farming and water accounted for 80% proportion in the ecosystem service value constitution; (3) among the contributions of various ecosystem functions to the ecosystem service value, the value of water conservation and waste disposal was the higher, which accounted for 40% of the total ecosystem service value; (4)the ecosystem service value sensitivity index of each land use type was less than 1, indicating that the ecosystem service value of Ganzhou District lacked flexibility, the results were credible; (5) ostensibly, the ecosystem service value changes directly originated from the land use/cover change, essentially, human activity intensity and the government policy guidance in different periods were the indirect-driving factors for the land use/cover change.
