In recent years，self-tourism has become a popular choice for the public，while its security issues have also received widespread attention from all walks of life. Based on the investigation and analysis of the security incidents of self-tourism in the whole country in 2018，it is found that self-tourism safety and the security situation in 2018 is rather grim and the number of security incidents has increased slightly，but the number of people involved has decreased significantly. The main types of security incidents are accidents and disasters，and the distribution of time，space and scenic spots shows a certain concentration. In 2019，the number of self-service tourists in China will continue to grow，and the security situation is still not optimistic. Based on the analysis of the current situation，characteristics and causes of self-tourism security incidents in 2018，this study suggests that self-tourism safety publicity and education should be strengthened；facilities and equipment should be improved and timely overhauled；emergency plans should be formulated，security personnel training and drilling should be carried out regularly；digital and intelligent construction of scenic spots should be accelerated；industry management should be strengthened to encourage the growth of third parties in self-tourism.
