Abstract: On the basis of a survey of farmers in desertification areas of Gansu Province, this thesis, employing Logit model, discusses the relations between the features of farmers in soil desertification areas and their perception of the environmental disasters risk from the perspective of environmental equity. Individually, the gender and marriage status have inconspicuous connections with the perception of risks of environmental disasters, while the educational level of farmers and the perception of risks of environmental disasters significantly demonstrate a positive correlation. In terms of economic features, the risk perception of environmental disasters of farmers is mainly reflected in the loss of land management income; the relations between the farmers’ perception of the environmental disasters risks and their annual household income present an inverted U-shaped trend. From the perspective of ecological features, the environmental governance strikingly lowers the perceivable environmental disasters risks. Through analysis, it is assumed that the unequal risks of environmental disasters posed on farmers is to some extent the reflection of the inequality they suffer in the social-economic realm, which is manifest in that: 1) from the perspective of individual characteristics, farmers aged 40-60 years and those more educated are more perceptive of environmental inequality; 2) from the perspective of economic characteristics, environmental inequality is mainly reflected by the impact of the risk of environmental disaster on land management income, and is associated with the income disparities among different groups that farmers with annual household income around 100 000 yuan are more sensitive to environmental inequality; 3) from the perspective of ecological characteristics, effective ecological governance is favorable for promoting environmental equality; however, farmers’ attitude towards environmental protection is not subject to ecological changes.
