In order to explore the changes in the landscape ecological security pattern of typical ecologically fragile areas, taking Wanzhou District as an example, we used landscape ecology, geostatistics and coupling coordination model to systematically analyze the temporal and spatial change characteristics and coupling coordination characteristics of landscape ecological security in Wanzhou District from 2009 to 2018 from the perspective of production-life-ecology. The results show that:(1)from 2009 to 2018, the ecological space of forest land dominated Wanzhou District with the rapid expansion of urban living space, a large reduction of agricultural production space, and a higher degree of land use;(2)the overall landscape ecological security in Wanzhou District was at a high level with a high spatial distribution in the central part and a low spatial distribution in the northeast to the southwest; the safe area concentrated in the town center with an obvious L-shaped distribution; the disturbed area mainly distributed along the Yangtze River Basin;(3)there is a strong positive spatial correlation between the landscape ecological security in Wanzhou District; the ‘high—high' cluster area mainly distributed in the town center, while the ‘low—low' cluster area mainly distributed in Ganning Town, Xiangshui Town and Longsha Town; the best fitting models are gaussian model and linear model;(4)the level of coupling and coordination of the landscape ecological security of the ‘production-life-ecological space' in the study area was not high, and the overall spatial distribution characteristics presented the high level in the middle and the low level in the surroundings; landscape ecological security in river regions had not yet achieved synchronous development in the ‘life -ecological' space, and the landscape ecological security in the town center was also in the unbalanced development stage in the ‘production-ecology' space. Therefore, it is of great significance for the future ecological construction and sustainable development of Wanzhou District to optimize the layout of various land use types, control the orderly expansion of urban living land, improve the stability and anti-interference of ecological land, and promote the coordinated development of production-life-ecological space ecological security.
