Explain the meaning of the system is the use of a media and expressions, so that specific information dissemination and reach among the recipients of information to help recipients understand the nature and characteristics of related things, and to achieve the basic functions of service and education. tour guide system The current problems of tourism interpretation system. Guide the quality of their own shortcomings Guided commentary system is currently my tourist attractions one of the main commentary. It is a dedicated tourist guide to tourists active, dynamic information transmission as the main expression. Therefore, the reliability and accuracy of the information provided by the WMS depends on the quality of the tour guides themselves. At present, tourist guides in many domestic scenic spots often lack specialized training on ecological knowledge of the scenic spots and lack adequate operational knowledge for the protection and education functions of tourism, making it hard for them to provide tourists with the services of protection and educational functions that ecotourism should possess . Interpretation of the sign display design has neglected the function of ecological protection, that is, the explanation signage is the explanation signage, which is the most basic and most widely used type of facilities in the explanation service. As far as scenic areas are concerned, narration signs can be categorized into the following four categories: traffic guidance signs, scenery explanation signs, warning advice signs and service guidance signs. First of all, in the design of the explanation signboard, there are many factors that contradict the ecological environment protection in the material selection, style, color and content of the explanation signboard of the current travel explanation system. As many of the signs of the area choose to use arsenic or copper treated wood as a preservative material, which itself has become a pollutant; part of the area of the licensing style and style of scenic spots and ecological protection are not coordinated; various types of signs and colors Miscellaneous and so on. Second, all kinds of explanatory signs show that text, graphics and grammar organizations are not humanized. At present, the interpretation of signs in most scenic spots in our country is weak with multilingual explanations. Foreign language grammars and improper usage of words are more common. Traffic identification routes are confused and inconspicuous, and graphic applications are not in conformity with norms. Scene explanations are too simple or too complicated to be read by tourists ; Vigilance advice signs tough language, resulting in psychological discomfort tourists; service guidance card is not clear enough. These problems have largely affected the tourist's interest in traveling, which is even more detrimental to the development of tourism ecological protection and educational functions. Visitor Center explains the weakness Many tourist attractions in the current tourist center focus on tourism distribution, reception and other functions and neglected as a global commentary function, part of the small area does not even set up tourist center interpretation facilities. This led to the tourists lack of scenic spots after the global understanding of a direct impact on the quality of tourists. Outdated content, the lack of knowledge of the content, especially the explanation of the content of the flaw is the current travel interpretation system, the biggest problem exists. China's tourism industry has entered a stage of great development of ecotourism, but most scenic spots explain the contents of the scenery still remain in the traditional tourism level. First of all, judging from the proportion of explanations, the pictorial descriptions and fantasy legends of the current tourist attractions occupy an important position and even a leading position. However, there is a relatively weak science-based and knowledgeable content about the scenery. At present, most of the explanations tend to take the pictographic rocks in the scenic area as the main body. Many legendary myths have been fabricated around these pictographic mountains and rocks. However, there are few geological, environmental, ecological and historical facts on these kinds of landscapes. Some of the sightseeing value is not high but the ecological and scientific value of the scene is often discarded as badly done, there is no explanation of glacial relics found is one of the typical example. It has become the need of the development of ecotourism to set up a system to explain the scene changing with the changes of the concept of time, season and social times. To sum up, there is a big problem in the current tourism interpretation system, and in many aspects, it is incompatible with the status quo of tourism development. How to transform the existing tourism commentary system and establish a tourist commentary system that adapts to the great development of ecotourism is imminent. The author of the current tourism interpretation system and the tourist system to explain the expectations of visitors in the area survey conducted a survey to grasp the current tourist attractions, especially ecotourism tourism tourist information system based on the first hand information on this basis The concept of tourism eco-commentary system.
