英文摘要	Rock exposure is a prerequisite for the emergence of bare rocky land (BRL), a severe ecological and environmental problem in karst mountain areas (KMA) of Southwest China, severely restricting the region's sustainable development. An in-depth analysis of the evolution of BRL in KMA of Southwest China based on socio-ecological perspectives is significant for promoting the region's sustainable development. This paper firstly analyzes the evolution of the social-ecological system and BRL and the transition of human-land relations in KMA of Southwest China, then selects a typical KMA, Huajiang Canyon in Guizhou Province, for a case study and applies ArcGIS to analyze the dynamics of the BRL of Huajiang Canyon in the past 60 years from 1969 to 2020, and reveals the reasons for the evolution of BRL. The results show that: (1) The evolution of BRL in KMA of Southwest China is closely related to the changes in the local socio-ecological environment. (2) The number, spatial distribution, and landscape pattern of BRL in the Huajiang Canyon from 1969 to 2020 underwent significant changes, with the area of BRL transitioning from an expansion phase to an accelerated shrinking phase and with prominent spatial dispersion characteristics. (3) The transition of the BRL of the Huajiang Canyon into forest grassland and economic and fruity forest land, and the transition of land use from production to ecology and ecoeconomy, have proved the greening of the KMA of Southwest China from a microscopic perspective. (4) This paper shows that the expansion and contraction of BRL areas can reflect the human-land relations in KMA of Southwest China. Finally, the development path proposed in this paper has a certain positive effect on promoting the future sustainable development of the KMA of Southwest China and can also provide a reference for developing other mountainous areas with similar situations.
