Abstract: The construction of language landscape for urban emergency services is an important part of public services. As a current city for the construction of Hainan Free Trade Port, Sanya City has a unique natural environment and is also a hotbed of various natural disasters in island cities. The challenges faced by emergency language services in Sanya City are not only how to effectively communicate emergency information to domestic citizens, but also how to cross language and cultural differences to ensure that all tourists can understand and follow emergency instructions. Against this background, it is of great significance to study the emergency language landscape of Sanya City.
