Abstract: Narrow the income gap among rural residents is positively significant for the implementation of the current rural revitalization strategy. Selecting the 2015 China General Social Survey （CGSS） data, this paper uses the intermediary model to examine the adjustment effect of heterogeneous social capital on the gender income gap of rural residents from three dimensions: social media, trust and social contact. The research finds that the current gender income gap of rural residents is significant. The social capital measured by social network can significantly adjust the gender income gap of rural residents, on the contrary, the trust dimension of social capital could restrain the adjusting effect to the gender income gap of rural residents. However, the adjustment effect of social capital with the dimension of social interaction on rural gender income gap is not significant. Therefore, it is necessary to distinguish different forms of social capital. Government should improve the social capital accumulation of rural residents by improving the social network construction in rural areas, by enhancing the awareness of rural residents' trust and risk prevention, and by encouraging rural residents to cross-regional mobility, so as to create favorable benefits for adjusting rural gender income gap.
