With the development of society and economy， the groups of vulnerable children in our country are getting larger and larger， and their types are diversified. Especially for vulnerable children in ethnic areas， relative economic lag brings new problems to the social service work of children in distress. Taking the survey of Liangshan Yi Districts as an example， this paper focuses on the study of external factors， internal factors， efficacy factors and other aspects of children in distress in Liangshan. By analyzing the disadvantaged children in ethnic areas from the strength perspective，we can obtain the data about the components of the resilience of Liangshan children in distress and open a new path for the Liangshan Children in distress with resilience fitting the region of the era.
