The construction of reservoirs has led to difficult livelihood transitions of resettled households after relocation and resettlement, resulting in a series of socioeconomic problems. How to scientifically integrate regional resource advantages and improve the livelihood resilience of resettled households has become an important problem to be solved to prevent and resolve social equity and justice risks and sustainable livelihood development. Taking Xiangjiaba Hydropower Station (Yunnan Reservoir area) as an example, the evaluation index system was constructed from the three dimensions of buffer capacity, self-organization capacity and learning capacity, the gray correlation degree method was used to evaluate index system, and the clustering method was selected to screen the indices that have a great impact on livelihood resilience. On this basis, the comprehensive index method was used to calculate the livelihood resilience, and the contribution degree model was used to identify the main contribution factors of livelihood resilience and to explore the path of livelihood construction to improve the livelihood resilience of resettled households.
