This paper is to explore the spatial-temporal coupling characteristics between the rural population in karst trough valley area and its cultivated land area, and reveal the transformation process of man-land relationship, so as to provide scientific reference for agricultural land regulation, ecological restoration, and rural revitalization in this area. Taking the classical area Yinjiang County as an example, we analyzed the features of the population and farmland change trend in Yinjiang, its spatial-temporal coupling relationship features and its driving forces behind by making use of the demographic data and land data in Yinjiang, during which the elastic coefficient model was employed. The results show that:(1)as a whole, the rural population and farmland in the karst trough valley area increased first and then decreased; the per capita arable land area decreased first and then increased;(2)the spatiotemporal coupling relationship between the rural population and farmland change in the karst trough valley experienced the dynamics from being unbalanced to being balanced; before 1990, the villages in the karst trough valleys were mainly unbalanced development, particularly with the unbalanced development type ofⅠand Ⅷ; after 1990, the trend was a balanced development type, with the balanced development type of Ⅳ and Ⅴ; the man-land relationship tended to be coordinated;(3)according to the coupling relationship of population and farmland change during 2000—2016, the karst trough valley area was divided into four types; each type scientifically coordinated the relationship between rural population and farmland by combining factors such as the characteristics of coupling types, natural geographical conditions and social and economic development. These results reveal significant changes of spatiotemporal coupling relationship between rural population and farmland in the karst trough valley area in the past nearly 60 years. The transition of the man-land relationship in rural areas has been come into being. With the above results, it is highly suggested that the farmland planning, the land resources distribution and the ecological restoration in the future should follow this trend in the karst trough valley area, so that the rural revitalization and a harmonious man-land relationship could be achieved.
