Abstract: Sustainable livelihood of immigrants is one of the key problems of solving poverty and fragile ec-ological environment of the Three Gorges Reservoir Area.Analyzing the present situation and differences of livelihood capitals between immigrants and aborigines can provide reference for making out correspond-ing measures to improve the livelihood condition.Under the guidance of DFID’s sustainable livelihoods a-nalysis framework,and based on the field survey data of the Three Gorges Reservoir area,evaluation index system of livelihood capitals has been established in this paper,and entropy evaluation method employed to calculate the evaluation index weight of immigrants and aborigines,and then the integrated scores of liveli-hood capitals calculated by the weighted average integrated model.On the basis of analyzing the character-istics of immigrants’and aborigines’livelihood capitals,independent samples t-test has been further applied to analyze the differences of livelihood capitals between immigrants and aborigines.The results show that the overall level of immigrants’and aborigines’human capital,social capital,natural capital,physical cap-ital and financial capital are low which could restrict the development of livelihood diversity.Additionally, the differences of five kinds of livelihood capitals between immigrants and aborigines aren’t statistically sig-nificant and to some extent they have strong homogeneity.Lastly,this paper simply discusses the related measures on improving the livelihood condition and enhancing the life quality of immigrants.
