Abstract: Objective analysis of the rural poverty differentiation mechanism and the stability of poverty alleviation in typical poverty-stricken counties is necessary to promote the effective implementation of Rural Revitalization. Taking Funan County in Anhui Province as a typical case, this article analyzes the causes of rural impoverishment in typical poverty-stricken counties by combining village and farmer scales, and discusses the connection mechanism between poverty alleviation stability and Rural Revitalization based on the characteristics of the study area. The results are as follows: (1) There are significant differences in the density of poverty-stricken villages in various towns of Funan County, with the overall trend of being dense outside and sparse inside, and some areas are concentrated in the core area, According to the nuclear density, the poor villages are divided into five primary core areas, four secondary core areas and five tertiary core areas.(2) From the village scale analysis, the development potential factors, such as the proportion of disabled households and sick households, and the location factors, such as the proportion of disaster, the distance to the county and Township Center, the distance to the main road and the average elevation of the village, are the leading factors affecting rural poverty; From the perspective of the scale of farmers, the attributes of administrative village, poor households, family size, whether the family has disabilities or diseases, the proportion of labor force and the proportion of migrant workers are the significant factors of poverty in the study area.(3) Based on the analysis of village level and peasant household level, it is the key to promote the sustainable development of poverty alleviation in the study area to develop characteristic agriculture in combination with regional resource endowment in order to enhance the endogenous driving force of poor villages and the livelihood level of poor households; This article discusses the connection mechanism between Rural Revitalization and targeted poverty alleviation from the five core points of industry, talent, culture, ecology and organization, aiming to provide the basis for the accurate implementation of Rural Revitalization in the region.
