The positive impact of tourism development on tourist destinations is best to have cases and analysis.

(A) the positive role of folk tourism in the destination

1. Accelerate the pace of poverty alleviation in ethnic areas.

"Strengthen the development of tourism resources in the central and western regions with good resource conditions and good market prospects, and promote the economic development of these regions with tourism." As early as the Ninth Five-Year Plan for Tourism Development in China and the Outline of 20 10 Long-term Goals, the National Tourism Administration put poverty alleviation through tourism on its important work agenda.

Most areas rich in folk customs and tourism resources in China are located in remote provinces, and their economic development is relatively backward. Moreover, the development of industry lacks resources; The inconvenient transportation limits them to take the road of developing business like coastal cities; There are mountains and canyons everywhere, and the scarce cultivated land limits the development of agriculture. However, because the communication with the outside world is almost isolated, the local folk customs are quite intact. Simple folk customs, strange buildings, charming costumes and unique diet have created their unique folk tourism resources. The development of folk custom tourism can make full use of the powerful driving characteristics of tourism, create employment opportunities for ethnic areas, reduce the employment pressure of population in ethnic areas, increase residents' income, raise local taxes, improve infrastructure construction and promote the development of local agricultural and sideline products. Of course, the final result of the development of these factors is the rapid economic development in ethnic areas, the gradual poverty alleviation of local residents and the gradual improvement of their living standards.

There are countless examples of this. For example, as a world cultural heritage, Old Town of Lijiang not only attracts tourists from all over the world with its magical and magnificent natural scenery, but also plays an increasingly important role in the development of tourism. A pattern of cultural industry consisting of Naxi ancient music, Dongba culture, folk culture and the protection of cultural sites has basically taken shape, creating an annual output value of more than 654.38 billion yuan for local governments [5].

2. Conducive to the protection and development of culture in ethnic areas.

With the development of folk tourism and the need to receive foreign tourists, some traditional customs and cultural activities that were almost forgotten in ethnic areas have been re-developed and restored; Traditional handicrafts have been re-developed due to the expansion of market demand; Traditional music, dance, drama, etc. Has been paid attention to and explored; The long-term endangered historical heritage has not only been reborn with the development of folk tourism, but also become a unique cultural resource that other tourist receiving countries or regions do not have.

The development of culture depends largely on the reorganization of existing cultural elements. Therefore, the more cultural elements there are in a society, the richer its cultural diversity, the more choices people have, and the greater the possibility of cultural innovation. Every nation can exist independently because they have a unique national culture different from other nations. This "culture" constitutes an important symbol of differences between countries. Reasonable protection of the diversity of folk culture can provide strong resource support for the sustainable development of China culture and maintain the sustained vitality and motivation of China cultural development. The vitality of a culture is an important symbol of its existence, and the development of traditional folk tourism resources is to inject lasting vitality into folk culture.

3. Promoting exchanges between countries and nations is conducive to equality, unity, prosperity and development of mankind.

People of different nationalities, different regions, different races and different countries will not only eliminate their prejudices and barriers, but also promote mutual learning and common progress through understanding and experiencing exotic elegance and exotic sentiment. Because "throughout the ages, every nation is superior to other nations in some aspects" [6]. People of different nationalities have the psychology of discrimination and distrust, one is due to well-known historical roots, and the other is due to the lack of communication and understanding between them. In this sense, the development of folk tourism plays a very important role in easing international relations and promoting the implementation of human peace in international affairs. Because folk tourism is a direct communication between people from different countries, different nationalities, different beliefs and different lifestyles, rather than information transmission and indirect communication represented by written media or individuals, it is more conducive to enhancing mutual understanding between people from different countries.
