“…The urgent situation of climate change, environmental crisis and deep poverty makes ecological migration research the focus of international organizations, governments and academic institutions. Foreign scholars have studied the theory and practice of ecological migration earlier, mainly focusing on the concept and classification of ecological migration [ 3 , 4 ], occurrence mechanism [ 5 , 6 , 7 ], the prediction of the subsequent development of migration [ 8 , 9 , 10 ], the relationship between ecological migration and environment [ 11 , 12 , 13 ] etc., and Chinese scholars pay more attention to the causes and purposes of ecological migration [ 14 ], sustainability and survival status of migrant society [ 15 ], social adaptation [ 16 ] and spatial evolution [ 17 ], ecological migration policy and management [ 18 ], economic benefits [ 19 ] and risk assessment [ 20 ], impact on the environment [ 21 , 22 ], etc. Over the past 30 years, with the continuous development of the practice of ecological migration, world scholars have conducted multi-level and all-round research on ecological migration from different disciplinary perspectives.…”
