ABSTRACT
In order to study the impact degree of tourism system of the Spring Festival holiday in China under the impact of the COVID-19, this article establishes the concept and theory of performance vulnerability of a system by using the concept of vulnerability in the measurement of the effect degree of a system under the impact of disturbance factors. Combined with AHP and compositive evaluation method, we set up a vulnerability evaluation index system of tourism system to measure the index of performance vulnerability of the tourism system and its subsystems under the impact of the COVID-19, and discuss the impact mechanism model of the COVID-19 on the tourism system during the Spring Festival. The research shows that: the index of performance vulnerability of the tourism system in Spring Festival holiday is 0.6560, which reaches high vulnerability;the index of tourist market system is 0.7250, which reaches high vulnerability;the index of transportation system is 0.6930, which reaches high vulnerability;the index of central tourism enterprise system is 0.8714, which reaches severe vulnerability;the index of destination system is 0.8024, which reaches severe vulnerability;The index of support system is 0.1368, which reaches slight vulnerability.
