Abstract: The protection and construction of ecological public welfare forests cannot be separated from the active participation of forest farmers. Based on the theory of planned behaviour, with Guangxi forest farmers as the specific research object, using random sampling method, in each county (city, district) randomly, this paper selected jurisdiction of the two townships (towns, streets) as the survey point, and the Logistic model was used to empirically analyse the influencing factors of forest farmers’ willingness to participate in the protection and construction of ecological public welfare forests. The results showed that, the age, source of livelihood, economic and social status, family income, and the cognitive evaluation of the functional role of ecological public welfare forests and ecological compensation status of forest farmers had a significant influence on their participation in the management and construction of ecological public welfare forests. Based on the conclusions of the study,this paper put forward following recommendations: increase the publicity of the protection and construction of ecological public welfare forests, continue to improve the forest literacy of forest farmers, strive to improve the compensation and subsidy standards of ecological public welfare forests, improve the rate of payment of financial compensation funds, broaden the channels for forest farmers to increase their income, and increase the sources of income of forest farmers.
