Cultural and natural heritage is an important sustainable development resource of the country, which can benefit future generations. It has dual values: first, the value of existence, including material value and research, appreciation and education value. It is the core and main value, which determines the principle of protection priority. The second is economic value, which comes from existence value, including direct economic value and indirect economic value. Existential value is the source and economic value is the flow. The greater the value of existence, the greater the potential economic value and the greater the direct economic benefits. Therefore, we must attach great importance to the protection of various important heritages, have a scientific and long-term plan, and carefully design various facilities around the scenic spot to make them harmonious and unified and protect the original value of the heritage.
(2) All kinds of tourist facilities in famous cultural and natural heritage scenic spots must be coordinated with the local national culture, so that the internal and external landscapes can complement each other and be integrated.
Most cultural and natural heritages are closely related to the local national culture. For example, Jiuzhaigou is named after nine Tibetan villages such as Lotus Leaf, Shuzheng and Zezawa, which are closely related to Tibetan culture and complement each other. Old Town of Lijiang is also a symbol of Naxi culture. Huangshan Mountain is associated with Huizhou culture. The purpose of people's travel is to appreciate the beauty of scenery and mountains and rivers, as well as the unique cultural customs of various ethnic groups and regions. Every tourist wants to travel to areas with different cultures from his hometown, stay in hotels with ethnic characteristics and taste different flavors of food. If local cultures are similar, the value and significance of tourism will be greatly weakened. Therefore, all kinds of buildings and facilities serving tourism around each scenic spot must have local national cultural characteristics. For example, the facilities around Jiuzhaigou must have Tibetan or Tibetan Qiang cultural styles, which makes people feel that entering this scenic spot is like entering another world. In this way, in addition to the original cultural and natural heritage, the buildings and facilities around each scenic spot also have strong national characteristics, which not only protect the original features of the scenic spot, but also protect and even increase its original value, making it more attractive, thus making the local tourism and cultural industries flourish.
Protecting cultural heritage should be advocated by our whole society. Cultural heritage benefits future generations. Local government departments and cultural tourism departments should unite to publicize the whole city and protect our homeland, which is to protect our living space.
