Mountain is a typical ecological environment type. Mountain agriculture is very important to ecological environment protection and poverty alleviation in mountainous areas. Based on the viewpoint,this paper combed the relevant foreign literature,and concluded that the foreign research mainly focused on the sustainability of the development of mountain agriculture and climate change,and the impact of the reduction of agricultural biodiversity on mountain agriculture. Taking the time axis as the main line and the viewpoint as the supplementary line,this paper summarized the domestic literature,and found that the research emphasis of mountain agriculture in China varied with the changes of the characteristics of the times in the initial period(1960-1990),the development period(1990-2000),and the peak period(2000 to present). It found that the research objects were gradually changing from macro to micro,showing a trend of diversified development. The research method shifted from qualitative research to quantitative research,and the research perspective from single industry research to industrial integration development research. Through the study of the literature,it was found that the late study of mountain agriculture should pay more attention to the coordination of mountain ecological environment and economic and social development,especially to strengthen the study of mountain agriculture and poverty alleviation,rural revitalization and beautiful rural construction. In addition,the study of the overlapping areas of mountain, hill and karst landforms should be strengthened so as to enhance the application of the study. Finally,in the study of the integration of agriculture and other industries,more in-depth exploration should be done in order to further enhance the economic,social,ecological and landscape benefits of agriculture.
