Abstract: There is a special group in urban afforestation project-farmers with "compound identity", i. e., as a trader in land circulation and a direct consumer outside forestry ecology engineering, studying the satisfaction of farmers with "compound identity" is of significance for the sustainable management and utilization of urban afforestation project. Based on the construction of a system with 5 dimensions and 24 evaluation indexes, fuzzy comprehensive evaluation method was used to evaluate the satisfaction of farmers in Beijing plain afforestation project. The results showed that the overall satisfaction value of farmers was 65.825, which was only in the state of " general satisfaction". The order was as the management effect > compensation effect > ecological benefits > social benefits > economic benefits, indicating that at a certain extent, the feature of "compound" identity made the satisfaction degree would focus on the expectation of forestry ecological engineering externality only after the " economic compensation" was effectively guaranteed, which was major difference of farmers' satisfaction between in urban afforestation engineering and in general forestry ecological engineering.
