摘要：Under the interference of a series of strong human activities, such as the rapid expansion of built-up land and massive infrastructure construction, the issue of landscape fragmentation in mountain cities has become highlighted. Therefore, the city of Guiyang in southwestern China is selected as a representative of a typical mountain city in this study. Multiple landscape fragmentation indices and the human disturbance index (HDI) are used to analyze the response of the landscape to human disturbances in a mountain city. The results reveal that the gradient zone with a relatively flat topography is a significant region for the substantial changes of the HDI and landscape fragmentation indices. The changes of the HDI and landscape fragmentation indices are found to be similar in the gradient zone of the slope, topographic relief, and topographic position index, but different in each gradient zone of the elevation. Positive correlations are found between the HDI and the landscape fragmentation indices except largest patch index (LPI) in most terrain gradient zones. The research results can be used as important indicators of ecosystem monitoring in mountain cities and provide a scientific basis for the landscape planning of mountain cities.
