To expplore the coordinated development of ecology and economy in the Three Gorges Reservoir area in the new era,based on relevant theories such as the change of center of gravity and the method of intermediate material conversion,we calculated the value of various ecological services and the position of center of gravity of GDP growth rate,urbanization rate,secondary industry added value and per capita fiscal budget expenditure in the Three Gorges reservoir area by each prefecture city in 2005,2010 and 2015. The dynamic changes and coupling relationships of the position of center of gravity were discussed. The results show that in the early five years,the center of supply and cultural service value were shifted to the southwest,the adjustment service value center was shifted to the northwest,the support service value center was shifted to the southeast,and the total ecological service value was shifted to the northeast; except for cultural service value,the offset distance of other service value center was relatively small; in the last five years,the five service value centers had been shifted to the northeast; except for the value of cultural services,the offset distance of other service value center was relatively large; during the study period,the offset direction of the center of gravity of the regional GDP growth rate were changed,and that of center of gravity of the rest of the socio-economic remained unchanged; the offset distance of the center of gravity of regional GDP growth rate and urbanization rate increased first and then decreased,that of per capita budget fiscal expenditure first decreased and then increased,and that of the added value of the secondary industry was almost unchanged; the overlap between the center of gravity of regional GDP growth rate and the total ecological service value first increased and then weakened,and the overlap between that of the remaining economic variables and the total ecological service value had increased year by year. The analysis showed that changes in forest area,water area,and construction land area are the main reasons for the changes in the value of ecological services in the early stage. At that time,the coupling between ecological environment and economy was weak,and human activities had the inverse effect on the environment; in the later stage,population concentration and industrial agglomeration were also influencing factors,and coupling was enhanced.
