对数百万人来说，旅游一直是最吸引人和最有趣的一种消磨时间的方式。旅游业作为一种产业，利润丰厚，被认为是各国的经济救星，特别是对那些从工业和经济发展来看不那么强大的国家来说，但它们的历史位置和丰富的建筑吸引了他们。旅游业，尤其是自然旅游业，不仅带来了经济价值，而且在生态上也相当危险，因为旅游业对国家生态的影响是消极的。本文主要讨论旅游对环境的影响，并与旅游业的生态影响进行讨论。
从环境的观点来看，旅游是自然使用的形式之一。旅游业的发展需要人类活动参与自然资源的开发。这产生了一种特殊的景观——休闲。在许多发达国家，用于娱乐和旅游业的地区在农业和林地面积之后排在第三位。全球旅游业的迅速增长及其巨大的经济效益使休闲利用土地，并有能力成功地竞争和取代其他用途。 旅游者关注的自然和领土脆弱脆弱，游憩资源有限，不可替代，机会有限。在工业化国家和发展中国家，它们自发和不合理的使用造成了旅游业发展领域的一些环境问题。
Tourism has always been one of the most attractive and interesting kinds of time spending for millions of people. Tourism, as an industry, is very profitable and is considered an economical savior for the countries, especially for those, which are not so strong from the point of view of industry and economic development, but are very attractive by their historical places and rich architecture. The tourism, especially the nature tourism, brings not only economic value; it is also rather dangerous ecologically, because tourism influence ecology of the countries in the negative way. The present paper is devoted to the discussion of the environmental impacts of tourism and contains discussion of economic benefits of tourism compared to its ecological impacts.
From an environmental point of view, tourism is one of the forms of nature usage. Tourism development requires an involvement of human activity in the natural resources. This produces a special kind of landscape - recreational. In many developed countries, areas used for recreation and tourism, are on the third place after the area of agricultural and forest lands. Rapid growth of the global tourism industry and its large economic benefits makes recreational use of land and promising ability to successfully compete and displace other uses.
Nature and territories of attention of tourists are vulnerable and fragile, and recreational resources are finite, they are irreplaceable and have limited opportunities. Their spontaneous and irrational usage creates a number of environmental problems in areas of intensive tourism development, both in industrialized countries and in developing countries.
For example, Mykonos Island in Greece is a famous tourist resort, during the last 30 years, that has rapidly developed. Together with the development of the tourism industry (accommodation, bars, etc.), the island's population has also increased, in contrast to other Greek islands, where the population has recently decreased. The main reason for the increase of the island population was the development of infrastructure (construction of ports, expansion of the network of roads, dykes, etc.). It also allowed more tourists and visitors to visit the island, leading to the gaps in such problems as traffic jams, lack of parking, increased crime, and pollution of water and land resources, especially in high season. At the same time, intensive construction, tourism and infrastructure development " absorbed " most of the island, and led to the loss of farmland. Uncontrolled and rapid development of tourism has led to a complete change of two traditional villages of the island, which were merged with the newly constructed villages, and turned into a large-scale residential areas, leading to degradation of the environment, local culture and changes in the socioeconomic structure (Mathieson and Wall, 2002)
The size of the negative impacts of tourism, which the economy of many countries is currently experiencing today, is huge and many countries do not have sufficient technical and financial capacity to replenish the resources used by tourists and for the disposal of their waste. Negative impacts of tourism on the environment, which has recently been underestimated, are now becoming an object of close attention of the international community. Such effects are varied and numerous : pollution of natural objects; consumption of natural resources; development of land; degradation of natural landscapes , threats to wildlife and habitats , with consequent loss of biodiversity , finally, the breakdown of local customs and social structures.
For example, Adriatic coast of Italy was devastated due to the rapid growth of brown algae. Because of the rising level of pollution due to excessive amount of tourists, the attractiveness of such a huge national park, as the Grand Canyon in the United States has significantly decreased. Some of the famous East African game parks have turned into a pile of dust by the tourists. Greece's national treasury, which used to be white marble Parthenon in Athens , is now a symbol of the neglect of the environment, suffered from the severe pollution. The government has taken the action to restrict the number of visitors to avoid the environmental catastrophe in the future.
Along with the burning problem of pollution and changing environmental components that are the most urgent in such recreational areas as national parks, nature reserves and suburban green areas, where attendance of tourists destroy leaves, twigs, pine needles, in other words , components containing essential nutrients. Disturbing the natural cycle and natural regeneration processes, and destroying underbrush undergrowth reduces biological activity of the soil and stands density. It leads to unbearable environmental problems and negative ecological impacts. Expansion of hospitality and the construction of a tourist destination (huge hotels; ports, making changes in the beach resort, but in the sea itself; specially setting the equipped stations for mountain tourism, etc.) have also a detrimental effect on the environment (Mathieson and Wall, 2002).
Experience Yellowstone National Park in the United States, one of the first "cradles" of tourism, illustrates the contradictory tendencies that the development of such tourism may lead to. On the one hand, the mass of visitors coming with the main purpose to visit Yellowstone provides a very substantial income for the entire state of Montana, where the park is situated: during their visit, they use other services, such as restaurants, gas stations and hotels (Gartner, 2006). However, the rapid growth of tourism seriously changed the way of life of the local citizens; they are ready to come up with it, because it will bring additional economic values to their region. Although the level of life of local residents, as well as those of the whole state, has slightly increased, they have to put up with the construction of new roads, road congestion and flow of tourists, noise pollution, gassy and rapid growth of prices for lands and properties. The concentration of visitors in the park reached a critical level, so communion with nature (the main purpose of their visit) has become almost impossible.
Negative aspects of tourism development in protected areas are more widely noticed than its positive aspects, as they are more obvious. Increase in the number of tourists, unsustainable use of natural resources, construction of hotels and other activities related to tourism, impact the environment in considerably.
It is necessary to admit that unsustainable intensive tourism development often leads to some local environmental catastrophes. Simultaneously, the development of tourism depends mainly on the quality of the environment and natural diversity. Water and air quality, aesthetics of landscape and biological diversity are the natural components of the tourism, reproducible result in the functioning of the natural ecosystems. There is hardly any kind of business, which is more interested in the preservation of all components of the environment than tourism is. While destroying the environment, tourism reduces the possibility of its development. There is a contradiction: how to resolve the problem? Are modern hospitality industry professionals look for the ways of solution?
Reasons for environmental concern 环境问题的原因
Transportation of international tourists is now carried out by planes, which annually consume a huge amount of kerosene. Thus, in 1990, 176 million tons of kerosene was used, while 550 million tons of CO2 and more than 3 million tons of NO2 has been extracted (this is a huge contribution to the "greenhouse effect" and acid rain, in its turn) (Andereck, 2003). Secondly, the usage of vehicles, which use gasoline and produce the same effect.
Construction and creation of infrastructure for the hospitality industry has led to an almost complete loss of tourist and recreational attraction in a number of places, such as Malaysia, the Caribbean, etc. Tourists and their behavior are also a powerful factor, having the negative impact on the environment. It can also lead to local environmental disasters: the catastrophic degradation of vegetation, erosion, landslides, loss of beaches, etc.
Positive economic impacts of tourism 旅游业的正面经济影响
Examples of negative impact of tourism on the environment are numerous, but at the same time, tourism can have a positive impact and contribute to the sustainable development, providing welfare and social progress. If the tourism is properly organized, it can make a significant contribution to the preservation of environment and culture. For example, together with the development of tourism over the past 50 years, a huge amount of parks and natural protected areas appeared (today there are nearly 10 000 national parks) (Johnson and Barry, 2002). Tourism is a powerful incentive for the creation of water treatment facilities, garbage disposal mechanisms, and favorable environmental conditions are the basic requirement for tourism. |
