The implementation of large-scale sand control pilot projects is an important means to curb the trend of land desertification and promote the coordinated development of ecology， economy and society in Gansu province. The study of farmers' satisfaction and influencing factors of large-scale sand control pilot projects is of far-reaching significance for objectively assessing the implementation effects of ecological management projects and promoting the sustainable development of regional sand control projects. This paper evaluates the satisfaction of farmers based on the CSI evaluation method and uses a binary Logistic model to analyze the influencing factors of farmers' satisfaction. The results show that the overall satisfaction of farmers with the project implementation is high， and the main reason for dissatisfaction is that the post-project management and care are not in place； After the project is completed and enters the nurturing stage， it is difficult to bring economic benefits into play in the short term； Variables such as education， average annual household income， and distance to the project area have a positive relationship with farmers' satisfaction； The scale of household land and the degree of natural risk in the sand area have a negative effect on farmers' satisfaction. If we look at the policy perspective， the implementation of post-project management and care efforts and the long-term mechanism of the project are the keys to improve the satisfaction of farmers.
