Abstract As a nonrenewable resource, geological heritage landscapes are formed in the process of geological processes. The fragility of the landscape is mainly determined by the external dynamic geological factors. The study of the Bamei stone forest, a unique metamorphic stone forest found in the Xianshuihe fault zone on the southeastern margin of the Tibetan Plateau, shows that the internal dynamic geological processes are also of great significance to its landscape vulnerability. Based on the implications of the formation of geological heritage landscapes and the landscape changes identified in the field investigations, in this study, we constructed an evaluation index system of the vulnerability of geological heritage landscapes based on a multifactor weighted evaluation. We included the geological background and human factors in the first level of the index; the five aspects of landscape genesis, geographical environment, climate conditions, economic activities, and protection activities in the second level of the index; and 14 other factors, such as tectonics, rock mass structures, rock types, geomorphical characteristics, vegetation, soil, hydrology, rainfall, temperature, wind force, infrastructure, land use, ideology, and protection measures, in the third level of the index. Using the analytic hierarchy process (AHP) to determine the index weights, the vulnerability of the metamorphic stone forest was evaluated scientifically, and the vulnerability levels and the trends of its strengths and weaknesses were determined. These results provide a feasible reference for the vulnerability evaluation of geological heritage landscapes. This index system has better systematism and comparability compared with the main qualitative research and sensory cognition in the recognition of geological heritage landscape vulnerability.
