Abstract：Taking Changyang Tujia Nationality Autonomous County,Hubei Province,as a case,this paper calculates the car-bon emissions of the County in the past 30 years after the construction of Geheyan Hydropower Station,and makes a prelimi-nary analysis on the impact of hydropower development.The results shown that in the past 30 years,carbon emissions in the County increased first and then decreased,from 0.420 9 million tons of CO2eq to 1.760 4 million tons of CO2eq(2010),and then decreased to 1.372 million tons of CO2eq(2017).The national carbon emission reduction policy has achieved initial results.In terms of important influencing factors of carbon emission,the scale of energy consumption in the early stage has changed to the structure of carbon emission,and the key source of carbon emission has changed to indirect emission,which indicates that the indirect carbon emission should be considered in regional carbon emission accounting in order to reflect the real situation of regional carbon emission After the development of hydropower,the development of Changyang County has experienced the trend of"improvement,deterioration,improvement,deterioration,continuous improvement".Through the improvement of industrial structure,the development has shown obvious characteristics of decoupling from carbon emissions,indicating that the hydropower development has brought opportunities for local low-carbon development.
