Abstract:: The objective of this study is to reveal the topographical distribution and evolutionary trend of the comprehensive fragmentation of karst mountainous landscape. We used topographic position index, distribution index, ecological landscape index and mean square error weight method to analyze the terrain gradient characteristics of the 25-year landscape fragmentation types in Guiyang. The results show that:(1)from 1990 to 2015, Guiyang City was dominated by high and general landscape fragmentation, which accounted for 42.51% and 30.36% in 1990, 41.33% and 30.56% in 2015, the area of high fragmentation decreased by 94.01 km², and the remaining three types of landscape fragmentation increased slightly;(2)low fragmentation and general landscape fragmentation mainly distributed in the middle, north and east of Guiyang City, and high fragmentation and severe fragmentation mainly concentrated in the west and south;(3)the fragmentation of various landscapes in Guiyang City had significant topographical characteristics; in 25 years, the cultivated land, water bodies and construction land were negatively correlated with the topography, cultivated land, water area and construction land in the 1～3 gradient all distributed in a dominant manner; the distribution indices of construction land and water area within the severe fragmentation degree were greater than 3, and the topographic characteristics were more obvious than that of cultivated land; the low-fragmented forest and grassland in the two phases were positively correlated with the terrain gradient, and both were dominant in the middle and high terrain, and the high terrain was the most prominent; the unused land and terrain gradients both increased first and then decreased, and unused land had the largest dominant distribution value at high gradients. This study has important practical significance for the objective and comprehensive understanding of the background of karst landscape fragmentation, provides basic data support for ecological environmental protection and land optimization, and can also enrich the research on the spatiotemporal evolution of landscape fragmentation in different terrains.
