Explicit carbon comprehensive compensation and its management type zoning are essential for the establishment of a watershed ecological protection compensation mechanism,which reflects the value of carbon sinks. Taking 10 counties (cities and districts) in the Qiantang River basin as the research area,this paper analyzes the spatial and temporal evolution of carbon emission and absorption at the county scale and its carbon balance relationship based on the carbon budget estimation. Taking into account the factors of social economy,resource utilization and ecological environment,it plans the carbon comprehensive compensation and management type zoning in the Qiantang River basin. The results shows that: 1) Carbon emission and carbon absorption in the Qiantang River basin were increasing from 2000 to 2020. Carbon emission showed a spatial pattern of "low in the southwest of China and high in the northeast",while carbon absorption showed a spatial pattern of "high in the southwest of China and low in the northeast". 2) The average Gini coefficient of carbon emission in the Qiantang River basin was 0.60 in 2000-2020,the economic contribution coefficient of carbon emission ranged from 0.86 to 1.03,and the carbon ecological carrying coefficient ranged from 0.02 to 15.81. The gap between economic development and resource utilization efficiency was large at the county level,and the mismatch between carbon supply and demand was relatively serious. 3) In 2020,Xiaoshan District,Yuhang District and Fuyang District were the balanced carbon compensation zone and the low carbon control zone,Changshan County,Kaihua County,Jiande City and Chun'an County were the compensated carbon compensation zone and the low carbon optimization zone,Lin'an District and Tonglu County were the compensated carbon compensation zone and the low carbon control zone,and downtown Hangzhou was the compensated carbon compensation payment zone and the low carbon emission reduction zone.
