In order to achieve sustainable development of farmers' livelihoods, quantifying the contribution rate of ecosystem services to farmers' livelihoods is necessary. The value of ecosystem services in the Three Gorges Reservoir Area assessed using the equivalent factor methodthe livelihood capital of vulnerability incorporated into the scope of farm household livelihood capital, and the livelihood evaluation system of farm households in the Three Gorges Reservoir Area constructed from six aspects: human, natural, physical, financial, social, and vulnerability, and the total livelihood capital of farm households measured. Linear fitting of the relationship between farmers' livelihoods and ecosystem services to analyze the impact of changes in the value of ecosystem services on farmers' livelihoods and the impact of changes in the amount of farmers' livelihood capital on ecosystem services, and then the results of domestic and foreign studies on the impact of ecosystem services on farmers' livelihoods. The results show that:(1)the total value of ecosystem services in 2019 of the Three Gorges Reservoir Area 209.365 billion yuan, among which the economic value provided by regulating services the highest and the value of cultural services the lowest, and the value of ecosystem services in Badong County the highest among all districts and counties;(2)the total amount of farm household livelihood capital in the Three Gorges Reservoir Area is 13.117, among which the amount of farm household financial capital the highest and the amount of natural capital the lowest, and the total amount of farm household livelihood capital in Jiangjin District the highest;(3)the household capital and ecosystem services in the Three Gorges Reservoir Area significant correlation, with the higher economic value provided by the ecosystem, farm household human capital, natural capital and financial capital show a change trend of rising and then falling, and farm household social capital a change trend of falling and then rising. Continuously leading farmers to pay attention to and participate in the ecological construction of the reservoir area, implementing agro-ecological circular development will help improve the contribution of ecosystem services to farmers' livelihoods in the Three Gorges Reservoir Area.
