This paper uses entropy to measure the resilience of Shandongs tourism economy, discusses its spatial pattern, and applies geographic detector and obstacle model to analyze its factors. The resilience of Shandongs tourism system is generally at a medium level, higher in Jinan, Qingdao, average in Yantai, Weifang, Linyi, Jining, and lower in northwest, southwest and southeast. It shows a “U-shaped” spatial pattern that Qingdao of high resilience and Jinan of relatively high resilience are connecting to southeast and east with medium resilience, the northwest is massively of low resilience. The spatial differentiation is mainly contributed by financial guarantee level (X1), resident consumption capabilities (X4), import & export level (X5). The chief obstacles against resilience are tourism major in university (D1),  tourism economy reconstructing capability (C2), and  tourism economy level (A2).
