The definition and connotation of eco-tourism Ceballos-Lascurain( 1988) points out that eco-tourism is a trip to a relatively undisturbed or polluted natural area, with a specific research theme, appreciation or experience of wild animals and plants, and attention to the cultural connotation found in this area. And fennell &; Smale( 1992) pointed out that a series of results, such as the change of human ethical beliefs on the environment and the awakening of natural environmental hazards, have led to the rise of another kind of selective tourism, namely, eco-tourism. Eco-tourism is an individual tourism different from mass tourism, a regional development and an activity that pays attention to local resources, economy, characteristics and life. Its main feature is to provide local resources and services. The economic prosperity brought by sightseeing activities belongs to local residents. Through the cooperation between supply and demand, local resources can be preserved and sightseeing and entertainment activities can be maintained. At the same time, local protection funds can be obtained to make the landscape resources sustainable development. Although there are different definitions of eco-tourism, after combing and summarizing this study, it is found that the definition and connotation of eco-tourism are actually similar. This paper also combs the definition of eco-tourism into two levels: cognition, eco-tourism is a tourism model developed under the principle of not damaging the environment, and its goal is to make the natural ecology and cultural traditional sightseeing resources sustainable. Emotionally speaking, eco-tourism is a kind of tourism with environmental responsibility, and its development goal is to protect the natural environment and care about the well-being of local residents. In a word, the connotation of eco-tourism is mainly to plan recreation bases and ecological resources available for recreation in selected natural areas, and to release the tourism model developed by linking it with neighboring socio-economic areas (Kurt Kutay, 1989), emphasizing responsible tourism in natural wilderness, which can not only protect the local ecological environment, but also enhance the well-being of local people. Two. The importance and principles of ecotourism. The Importance of Eco-tourism From the definition of eco-tourism, we know that it mainly solves and coordinates the problems among natural ecology, sightseeing and regional development. We hope that tourists can enjoy colorful entertainment experiences without destroying the natural environment, and at the same time respect local culture and take care of local residents, so that our sightseeing can be sustainable. However, these three problems affect each other, are closely related, and can also be said to be a whole, and it is absolutely impossible to solve any one problem. But if it is not solved properly, it will also bring many hidden worries and unimaginable consequences. It can be seen that the development of eco-tourism is not a slogan, but requires people to work together and put it into practice. We all know that there is only one earth, and so are all the resources on the opposite earth, including natural resources and natural ecological environment. If they are destroyed or mismanaged, it will have irreparable consequences. However, the ultimate victim is ourselves, so we should cherish our natural resources. After all, they can be rebuilt by non-human abilities, but we can't live without them. Only when natural resources and ecological environment are protected can people continue to survive, otherwise, not to mention sightseeing. Therefore, it is particularly important to carry out the concept of eco-tourism while there is still time at this stage, so that tourism and environmental protection can be carried out at the same time. The concept of killing two birds with one stone and benefiting others is of course particularly important. People should also promote the concept of eco-tourism through various channels and ways, so that people all over the world can work together to safeguard the natural environment on which we depend as soon as possible. These channels and ways can be diversified and go hand in hand, not just some people or institutions. From the experience of others, we can see the necessity and demand of ecotourism development. Tian Jiaju (2002) took Foshan Botanical Garden as an example to study the relationship between tourists' environmental awareness and behavior in eco-tourism areas. The research shows that tourists in eco-tourism areas are highly educated, and most of them have eco-tourism related experiences, and most of them are friends, classmates and colleagues. In terms of tourism motivation, people mainly appreciate the beautiful scenery of nature and admire the people who come here. Most of them hope to have professional tourism methods to explain and understand nature during their travels, which shows that people can better meet the needs of tourists for planned eco-tourism. According to Chen Binghui's (2002) research, taking Daxueshan forest recreation area as an example, this paper investigates the influence of tourists' environmental attitude on eco-tourism, and shows that environmental education can really stimulate tourists' travel attitude and behavior, make people closer to nature and learn to appreciate the beauty and value of nature. The study also shows that people who have received eco-education and participated in eco-societies are willing to cooperate with many norms and restrictions of the park, which shows that eco-tourism education is one of the important and inevitable ways to promote eco-tourism concepts. However, more and more research examples like the above show the importance of ecotourism, and most tourists are very willing to accept the concept of ecotourism and put it into practice as long as they are properly arranged, but there are some principles about ecotourism that we must carefully consider before implementing. (II) Principles of Eco-tourism As can be seen from the above, the importance of eco-tourism cannot be ignored and it is the development trend of tourism in the future. Therefore, in addition to understanding the definition, connotation and importance of ecotourism, the development of ecotourism should aim at protecting the natural ecology and ensuring local well-being, and follow the following principles (White Paper on Ecotourism, 2002): 1. Before developing eco-tourism, we should plan a whole set of regional sightseeing and tourist management plans in advance. 2. Before developing ecotourism, we should investigate and analyze the local natural and cultural characteristics in advance, evaluate the possible positive and negative impacts of tourism development, and make long-term management and monitoring plans to minimize the possible negative impacts.
