Ecological compensation is an effective method to coordinate the harmonious development of economy and resource environment and to resolve the contradiction between  ecological environment and economic growth. It has profound significance for promoting the construction of ecological civilization. Based on the survey data from farm households  in five cities in Yunnan Province, this research, using bivariate Probit model, analyzed key influencing factors of farmers’ willingness to pay(WTP) for ecological compensation  and their discrepancies in the forestry ecological function areas. The results showed that most farmers were willing to pay for ecological compensation; main factors that  affected their WTP included: gender, age, concurrent business, family population, the proportion of offfarm income, the cognition of importance of ecological compensation,  whether the economic benefit of forests is more important than its ecological benefit, their satisfaction with ecological environment, whether the government has advocated  ecological compensation as well as the degree of access to information. Age, household agricultural labor force and the degree of access to information had an importance  influence on farmers’ WTP; family population, the proportion of offfarm income and government compensation played a major role in influencing households’ WTP; four factors,  whether having concurrent business, the proportion of offfarm income, the degree of understanding of ecological compensation and access to information, had more significant  influence on WTP of traditional farmers; trust on policy implementation and industrial development situation have played an important role. Therefore, this research put forward  the following specific countermeasures: improving government service function in rural employment, encouraging farmers taking offfarm employment and entrepreneurship,  improving the construction of environmental education system in ecological function areas, promoting farmers’ environmental protection consciousness, strengthening government  responsibility and policy promotion and enforcement, building a comprehensive and ameliorated publicity medium of ecological compensation, as well as establishing and  implementation of differentiated ecological compensation measures.
