[Objective] The vulnerability and influencing factors of the social-economic-ecological system at tourism destinations in the Beijing-Tianjin-Hebei ecological conservation area were analyzed in order to provide a scientific support for reducing vulnerability and achieving sustainable development of the tourism destinations in the area. [Methods] Based on the social

economic and ecological subsystems

a comprehensive evaluation system of the vulnerability of tourism destinations in Beijing-Tianjin-Hebei ecological conservation area was constructed. Linear weighting method

natural breakpoint method and obstacle degree model were introduced to analyze the vulnerability and influencing factors of 23 county-level unit tourism destinations in Beijing-Tianjin-Hebei ecological conservation area in 2017. [Results] The average value of the comprehensive vulnerability index of the study area was 0.271 0

showing a mild vulnerability state. The distribution of social vulnerability

economic vulnerability and ecological vulnerability index of each study unit had obvious spatial differences

and was spatially concentrated. The grain output per unit area

urban-rural income gap ratio

industrial structure diversification index

per capita disposable income

and rural employees were the main factors influencing the vulnerability of tourism destinations in conservation areas. [Conclusion] At present

the overall sustainable development capacity of the study area is relatively good. Through the effective identification of factors influencing its vulnerability

countermeasures and suggestions

including grasping development opportunities

narrowing the gap between urban and rural areas

optimizing industrial structure and strengthening regional linkages

should be considered.
