英文摘要：

In the paper, we focus on the rural communities that were formed because of the implementation of the immigration and resettlement project in southern Shaanxi province. Based on the summary of the problems in the building of communities for resettling immigrants in the past three years in Ankang city, the orientation of rural communities that were formed under the background of immigration project was illustrated in a reasonable way. Besides, we analyze the influence of supporting facilities, industrial structure, ecological protection, residents＇ sense of belonging and identity, and community administration on the size of communities for resettlement from three sustainable aspects： economy, ecology and society. The grading system for the size of rural communities in southern Shaanxi province for resettling immigrants was determined by borrowing the grading standard for the size of villages in Shaanxi province, which will provide theoretical and practical reference for the Immigration and Resettlement Project in southern Shaanxi province.
