中文摘要：

在文化建设中，少数民族文化的保护是一项极其重要的工作。以哈尼族为代表的边疆少数民族出现规律性的人口流动，概括为“节日性候鸟迁徙”现象，并分析了哈尼族在人口流动增强情况下的文化变迁及其影响。研究认为，农民工的大量流动给曾经安宁的民族村寨带来了一些前所未有的社会影响，包括留守老人生活得不到有效保障、留守儿童的教育存在问题、作为农业文化遗产的哈尼梯田无人耕作、民族传统文化面临濒危等。

英文摘要：

Protection of minority cultures is an extremely important work in cultural construction. Population migration of the frontier minorities represented by the Hani has been on the rise in recent years and has a seasonal feature around festival time. The author analyzes changes in Hani culture and its impacts in the context of population mobility enhancement. The study suggests that large flows of migrant workers have brought unprecedented social impact on the once peaceful ethnic villages, causing problems in respects like security of the life of the elderly left behind, education of the left behind children, cultivation of Hani terraces which is known as the agriculture heritage of the Hani People, the maintenance of traditional national culture, etc.
