Abstract:: It is helpful to objectively identify the sensitivity and self-recovery ability of regional ecological environment to explore the spatiotemporal differentiation characteristics of ecological space vulnerability, and provide a basis for national spatial planning. Based on the VSD model, we constructed an ecological spatial vulnerability analysis framework in the Three Gorges Reservoir area, and analyzed the spatial and temporal characteristics and rules of ecological space vulnerability in the three Gorges Reservoir area from 2005 to 2018 from the perspectives of spatial exposure, spatial sensitivity and spatial adaptation. The results show that:(1)the three dimensions of ecological space vulnerability in the Three Gorges Reservoir Area had significant spatial distribution characteristics and time evolution law; the ecological spatial exposure in the main urban area of Chongqing(average 0.355)and Wanzhou District of northeast Chongqing(0.416)showed a double-core decreasing trend; it continued to increase from 0.235 6 in 2005 to 0.269 1 in 2018; the ecological spatial sensitivity of Wuxi County in northeast Chongqing was 0.691, while that of Beibei District was 0.296, increased from 0.360 7 in 2005 to 0.437 4 in 2018; the distribution of ecological spatial adaptation was high at both ends and low in the middle, with the main urban area of Chongqing(0.634 on average)and Yiling District of Hubei Province(0.613)as the double core; after decreasing from 0.518 4 in 2005 to 0.457 4 in 2010, it increased to 0.571 in 2018;(2)The extremely vulnerable ecological spatial regions of the Three Gorges Reservoir area mainly distributed in the southwest of the main urban area of Chongqing(average 0.735)and Wanzhou District of Chongqing(0.814), which showed an ‘inverted U' evolution law chronologically, increased from 0.336 2 in 2005 to 0.378 9 in 2015 and then decreased to 0.344 2 in 2018;(3)the temporal and spatial variation of ecological spatial vulnerability in the Three Gorges Reservoir area was a dynamic process, which was closely related to the intensity of human activities and natural conditions, and closely related to soil erosion intensity, slope, wastewater discharge, industrial structure and other natural environment and social and economic factors; meanwhile, the reservoir ecosystem had the strong self-repair ability.
