Abstract:After the boost by anti-poverty policies at different stages in Liangshan Yi Autonomous Prefecture, the vast majority of impoverished Yi people have rid of poverty and become better-off, and Liangshan region now enjoys a strong economic development momentum. However, the depressed situation of Yi people in high mountain areas has not changed much and people there still suffer from poverty because of poor natural conditions, difficult infrastructural constructions and scarce public services. To solve the problem, some Yi people in mountainous areas begin to immigrate spontaneously to relatively advantageous areas and the majority of them have been relieved of poverty.
