Abstract: [Objective] Taking foresters who are taking part in forest carbon sequestration project in Sichuan Province as research objects, this paper analyzed foresters'constant participation willingness and its affecting factors in order to provide countermeasures and suggestions for increasing foresters' enthusiasm to constantly participating forest carbon sequestration project, realizing the construction goal of project and speeding up sustainable development of forestry which is regarded carbon sequestration as the main objective in dealing with global climate change.[Method] Based on the survey data of 397 foresters in Novartis forestry carbon sequestration, community and biodiversity project construction zone in the southwest of Sichuan Province, the orderly Probit model was used to conduct an empirical analysis on foresters' constant participation willingness for forest carbon sequestration project and its affecting factors.[Result] The research results indicated that the willingness of foresters to constantly participate in forest carbon sequestration project was not high, and need to be further improved. The parameters such as land area of participation, family income level, satisfaction for early returns, the late earnings forecast, government support, the degree of difficulty in obtaining the forestry information and road traffic etc. haves significant positive influences on foresters' willingness of constant participation. While the age, multiple occupations level and project organization model showed significant negative effects.[Conclusion] We put forward some suggestions to promote the sustainable development of forest carbon sequestration projects from both business and government. For the forestry entity (enterprise), they should carry out multiple targets considering area, land and population, adjust measurements for local conditions to optimize the organization model of project, balance the early earns and late benefits. As for the government, they should intensify policy support, establish and perfect the forestry information release and disaster warning mechanism, introduce financial support policy to improve infrastructure construction of forest carbon sequestration project area. In this way, the sustainable development of forest carbon sequestration project would be promoted, and then realize the climate improvement, ecological prosperity and income increasing of foresters.
